SN74HCT08PW

Inverter Gates Overview

The SN74HCT08PW is a quadruple 2-input positive-AND gate manufactured by Texas Instruments in a 14-pin TSSOP package. It operates within a supply voltage range of 4.5V to 5.5V, featuring TTL-voltage compatible inputs and outputs capable of driving up to 10 LSTTL loads. The device provides ±4mA output drive at 5V with low power consumption (20µA max ICC). Typical propagation delay is 13ns at 5.5V, while maximum switching delays reach 27ns. Input capacitance is typically 10pF.

Inverter Gates FAQ

What is the recommended handling procedure for unused inputs?

All unused inputs must be connected to either VCC or GND to prevent undefined operational states caused by floating voltages.

How should bypass capacitors be installed for optimal performance?

A 0.1-μF capacitor is recommended for each VCC terminal, installed as close to the power terminal as possible to prevent power disturbances.
