ON DELAYS tPLH = tPHL N AND FUNCTION COMPATIBLE WITH 54/74LS14 B1R (Plastic Package) F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) DESCRIPTION The M54/74HCT14 is a high speed CMOS HEX SCHMITT INVERTER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. Pin configuration and function are the same as those of the HCT04 but all inputs have 0.7 V hysteresis level.This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fall input signals. This integrated circuit has input and output characteristics that are fully compatible with 54/74 LSTTL logic families. M54/74HCT devices are designed to directly interface HSC2MOS systems with TTL and NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of power consumption.All inputs are equipped with pro- ORDER CODES : M54HCT14F1R M74HCT14M1R M74HCT14B1R M74HCT14C1R PIN CONNECTIONS (top view) INPUT AND OUTPUT EQUIVALENT CIRCUIT NC = No Internal Connection October 1993 1/9 M54/M74HCT14 TRUTH TABLE A L H Y H L IEC LOGIC SYMBOL PIN DESCRIPTION PIN No 1, 3, 5, 9, 11, 13 2, 4, 6, 8, 10,12 7 14 SYMBOL 1A to 6A 1Y to 6Y GND VCC NAME AND FUNCTION Data Inputs Data Outputs Ground (0V) Positive Supply Voltage LOGIC DIAGRAM/WAVEFORM ABSOLUTE MAXIMUM RATINGS Symbol VCC VI VO IIK IOK ICC IO or IGND PD Tstg TL Supply Voltage DC Input Voltage DC Output Voltage DC Input Diode Current DC Output Diode Current DC Output Source Sink Current Per Output Pin DC VCC or Ground Current Power Dissipation Storage Temperature Lead Temperature (10 sec) Parameter Value -0.5 to +7 -0.5 to VCC + 0.5 -0.5 to VCC + 0.5 20 20 25 50 500 (*) -65 to +150 300 Unit V V V mA mA mA mA mW o o C C Absolute Maximum Ratings are those values beyond which damage to the device may occur.
