DM74LS153N

Signal Switches, Multiplexers, Decoders Overview

The DM74LS153N is a dual 1-of-4 line data selector/multiplexer manufactured by onsemi in a 16-lead Plastic Dual-In-Line (PDIP) package. It integrates inverters and drivers for binary decoding to AND-OR-invert gates, featuring separate strobe inputs for each section. Common select inputs A and B control both sections. Recommended operating conditions specify a supply voltage of 4.75V to 5.25V and an operating temperature range of 0°C to +70°C. Typical propagation delays are 14ns from data, 19ns from strobe, and 22ns from select.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering code suffix against current manufacturer documentation to confirm package type and reel options. The 'N' designation indicates a PDIP package; ensure compatibility with existing PCB footprints. Confirm availability status as this component may be subject to lifecycle changes or obsolescence notices.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent 4-line multiplexing is required within a single package. Ensure the application operates within the 0°C to +70°C temperature range and utilizes a 5V logic supply. Verify that the TTL-compatible input levels meet system requirements for HIGH and LOW voltage thresholds.
