1 / 9 page M54HCT08 M74HCT08 February 1993 QUAD 2-INPUT AND GATE B1R (Plastic Package) ORDER CODES : M54HCT08F1R M74HCT08M1R M74HCT08B1R M74HCT08C1R F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) PIN CONNECTIONS (top view) NC = No Internal Connection INPUT AND OUTPUT EQUIVALENT CIRCUIT . HIGH SPEED tPD = 12 ns (TYP.) AT VCC =5 V . LOW POWER DISSIPATION ICC =1 µA (MAX.) AT TA =25 °C . COMPATIBLE WITH TTL OUTPUTS VIH = 2V (MIN.) VIL = 0.8V (MAX) . OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS . SYMMETRICAL OUTPUT IMPEDANCE IOH =IOL = 4 mA (MIN.) . BALANCED PROPAGATION DELAYS tPLH =tPHL . PIN AND FUNCTION COMPATIBLE WITH 54/74LS08 The M54/74HCT08 is a high speed CMOS QUAD 2-INPUT AND GATE fabricated in silicon gate C 2MOS technology. It has the same high speed per- formance of LSTTL combined with true CMOS low power consumption. The internal circuit is com- posed of 2 stages including buffer output, which gives high noise immunity and stable output. All in- puts are equipped with protection circuits against static discharge and transient excess voltage. This integrated circuit has input and output charac- teristics that are fully compatible with 54/74 LSTTL logic families. M54/74HC devices are designed to directly interface HSC 2MOS systems with TTL and NMOS components. They are also plug in replace- ments for LSTTL devices giving a reduction of power consumption.
