SN74HCS365DR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCS365DR is a hex buffer and line driver featuring Schmitt-trigger inputs and three-state outputs. It operates within a supply voltage range of 2 V to 6 V, supporting an extended ambient temperature range from -40°C to +125°C. The device provides balanced CMOS push-pull outputs with typical drive capabilities of ±7.8 mA at 6 V. Propagation delay ranges from 4 ns to 32 ns depending on voltage and temperature. Static supply current is typically 2 µA.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Schmitt-trigger architecture affect input handling?

The Schmitt-trigger inputs provide hysteresis, making the device tolerant to slow transition rates and noisy signals, which prevents false triggering.

What is the function of the OE1 and OE2 pins?

OE1 and OE2 are active-low output enable pins. When either pin is high, all outputs enter a high-impedance state regardless of the input signals.
