| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information Analog Multiplexers/ Demultiplexers with Address Latch MC74HC4351A High-Performance Silicon-Gate CMOS The MC74HC4351A utilizes silicon-gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. These analog multiplexers/demultiplexers control analog voltages that may vary across the complete power supply range (from VCC to VEE). The Channel-Select inputs determine which one of the Analog Inputs/ Outputs is to be connected, by means of an analog switch, to the Common Output/Input. The data at the Channel-Select inputs may be latched by using the active-low Latch Enable pin. When Latch Enable is high, the latch is transparent. When either Enable 1 (active low) or Enable 2 (active high) is inactive, all analog switches are turned off. The Channel-Select and Enable inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The device has been designed so the ON resistance (Ron) is more linear over input voltage than Ron of metal-gate CMOS analog switches. For multiplexers/demultiplexers without latches, see the HC4051A, HC4052A, and HC4053A. * * * * * * * * Fast Switching and Propagation Speeds Low Crosstalk Between Switches Diode Protection on All Inputs/Outputs Analog Power Supply Range (VCC - VEE) = 2.0 to 12.0 V Digital (Control) Power Supply Range (VCC - GND) = 2.0 to 6.0 V Improved Linearity and Lower ON Resistance than Metal-Gate Types Low Noise In Compliance with the Requirements Defined by JEDEC Standard No. 7A * Chip Complexity: 222 FETs or 55.5 Equivalent Gates 20 1 N SUFFIX PLASTIC PACKAGE CASE 738-03 20 1 DW SUFFIX SOIC PACKAGE CASE 751D-04 20 1 DT SUFFIX TSSOP PACKAGE CASE 948E-02 ORDERING INFORMATION MC74HCXXXXAN Plastic MC74HCXXXXADW SOIC MC74HCXXXXADT TSSOP PIN ASSIGNMENT MC74HC4351A X4 X6 NC X X7 X5 ENABLE 1 ENABLE 2 VEE GND 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 VCC X2 X1 X0 X3 A NC B C LATCH ENABLE NC = NO CONNECTION This document contains information on a new product.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the ranges indicated in the Recommended Operating Conditions. Unused digital input pins must be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused Analog I/O pins may be left open or terminated. See Applications Information. * Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the Recommended Operating Conditions.

VCC being recognized as a logic high and GND being recognized as a logic low. In this example: VCC = + 5 V = logic high GND = 0 V = logic low The maximum analog voltage swings are determined by the supply voltages VCC and VEE. The positive peak analog voltage should not exceed VCC. Similarly, the negative peak analog voltage should not go below VEE. In this example, the difference between VCC and VEE is ten volts. Therefore, using the configuration in Figure 16, a maximum analog signal of ten volts peak-to-peak can be controlled. Unused analog inputs/outputs may be left floating (i.e., not connected). However, tying unused analog inputs and outputs to VCC or GND through a low value resistor helps minimize crosstalk and feedthrough noise that may be picked up by an unused switch. Although used here, balanced supplies are not a requirement. The only constraints on the power supplies are that: VCC - GND = 2 to 6 volts VEE - GND = 0 to - 6 volts VCC - VEE = 2 to 12 volts and VEE v GND When voltage transients above VCC and/or below VEE are anticipated on the analog channels, external Germanium or Schottky diodes (D x ) are recommended as shown in Figure 17. These diodes should be able to absorb the maximum anticipated current surges during clipping. +5 V +5V -5V 20 ANALOG SIGNAL +5 V 7 8 9 10 -5 V 15 13 12 11 TO EXTERNAL CMOS CIRCUITRY 0 TO 5 V DIGITAL SIGNALS VEE ON ANALOG SIGNAL +5V -5V Dx Dx VCC VCC 20 ON/OFF VCC Dx Dx VEE VEE 9 10 Figure 16.
