BALANCED PROPAGATION DELAYS tPLH = tPHL PIN AND FUNCTION COMPATIBLE WITH 54/74LS14 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- B1R (Plastic Package) F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) 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 IEC LOGIC SYMBOL A Y L H H L PIN DESCRIPTION PIN No 1, 3, 5, 9, 11, 13 2, 4, 6, 8, 10,12 SYMBOL 1A to 6A NAME AND FUNCTION Data Inputs 1Y to 6Y Data Outputs 7 GND Ground (0V) 14 VCC Positive Supply Voltage LOGIC DIAGRAM/WAVEFORM ABSOLUTE MAXIMUM RATINGS Symbol ICC Value Unit VCC VI Supply Voltage DC Input Voltage Parameter -0.5 to +7 -0.5 to VCC + 0.5 V V VO DC Output Voltage -0.5 to VCC + 0.5 V IIK DC Input Diode Current ± 20 mA IOK DC Output Diode Current ± 20 mA IO or IGND DC Output Source Sink Current Per Output Pin DC VCC or Ground Current ± 25 ± 50 mA mA PD Power Dissipation 500 (*) mW Tstg TL Storage Temperature Lead Temperature (10 sec) -65 to +150 300 o o C C Absolute Maximum Ratings are those values beyond which damage to the device may occur.
