This document describes the features and characteristics of the 74HC/HCT251 8-input multiplexer, including true and complement outputs, 3-state outputs, multifunction capability, etc.
The document is a product specification datasheet for the 74HC/HCT251, an integrated circuit described as a high-speed Si-gate CMOS device. It functions as an 8-input multiplexer with 3-state outputs, allowing for further expansion by tying outputs together when disabled.
| Device Type | 8-input multiplexer; 3-state |
|---|---|
| Technology | high-speed Si-gate CMOS |
| Output Capability | standard |
| Logic Category | MSI |
| Supply Voltage (HC) | GND to Vcc |
| Supply Voltage (HCT) | GND to Vec - 1.5 V |
The device provides both true and complement outputs.
The OE input controls whether the outputs are active or in a high impedance state, and it operates when set to a LOW voltage level.
This device functions as an 8-input multiplexer that combines signals from eight lines into a single line.
The HCT version can operate in temperatures ranging from -40 to +125 degrees Celsius.
