74AHC1G66; 74AHCT1G66
Single-pole single-throw analog switch
Rev. 04 -- 18 December 2008 Product data sheet
1. General description
74AHC1G66 and 74AHCT1G66 are high-speed Si-gate CMOS devices. They are single-pole single-throw analog switches. The switch has two input/output pins (Y and Z) and an active HIGH enable input pin (E). When pin E is LOW, the analog switch is turned off.
2. Features
I Very low ON resistance: N 26 (typ.) at VCC = 3.0 V N 16 (typ.) at VCC = 4.5 V N 14 (typ.) at VCC = 5.5 V I High noise immunity I Low power dissipation I Balanced propagation delays I Multiple package options I ESD protection: N HMB JESD22-A114E exceeds 2000 V N MM JESD22-A115-A exceeds 200 V N CDM JESD22-C101C exceeds 1000 V I Specified from -40 C to +85 C and -40 C to +125 C

To avoid drawing VCC current out of pin Z, when switch current flows in pin Y, the voltage drop across the bidirectional switch must not exceed 0.4 V. If the switch current flows into pin Z, no VCC current will flow out of terminal Y. In this case there is no limit for the voltage drop across the switch, but the voltage at pins Y and Z may not exceed VCC or GND. Applies to control signal levels.

At supply voltages approaching 2 V, the analog switch ON resistance becomes extremely non-linear. Therefore it is recommended that these devices be used to transmit digital signals only, when using this supply voltage.

All typical values are measured at VCC = 2.0 V, VCC = 3.3 V, VCC = 5.0 V and Tamb = 25 C. tpd is the same as tPLH and tPHL. ten is the same as tPZL and tPZH. tdis is the same as tPLZ and tPHZ. CPD is used to determine the dynamic power dissipation PD (W). PD = CPD x VCC2 x fi + ((CL x CSW) x VCC2 x fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; CSW = maximum switch capacitance in pF (see Table 7); VCC = supply voltage in Volt; ((CL x CSW) x VCC2 x fo) = sum of outputs.
