M74HCT32TTR中文资料意法半导体数据手册PDF规格书

DESCRIPTION

The M74HCT32 is an high speed CMOS QUAD 2-INPUT OR GATE fabricated with silicon gate C2MOS technology.

The internal circuit is composed of 2 stages including buffer output, which enables high noise immunity and stable output.

The M74HCT32 is designed to directly interface HSC2MOS systems with TTL and NMOS components.

All inputs are equipped with protection circuits against static discharge and transient excess voltage.

■ HIGH SPEED: tPD = 13ns (TYP.) at VCC = 4.5V

■ LOW POWER DISSIPATION: ICC = 1µA(MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS : VIH = 2V (MIN.) VIL = 0.8V (MAX)

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN)

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 32
