CD74HCT153E

Overview

The CD74HCT153E is a high-speed CMOS logic dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -55°C to +125°C. The device features two independent multiplexers, each with four data inputs, two select lines, and one enable input. It utilizes a 16-pin Dual In-Line Package (PDIP) for through-hole mounting. The output provides true signals with a maximum propagation delay of 51 ns. Output drive capability is specified at 4mA for both high and low states.
