SN74HC153ANSR

Overview

The SN74HC153ANSR is a dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to +85°C. The device utilizes a 16-pin Small Outline Package (NS). Key electrical characteristics include a maximum propagation delay of 38 ns at 4.5 V, output drive capability up to 15 LSTTL loads, and low power consumption with a maximum ICC of 80 μA.

Feature Summary

• Dual independent multiplexing channels sharing common address select inputs
• Full binary decoding for selecting one of four data sources per channel
• Individual strobe (enable) inputs for each channel to control output states

Applications

• Data routing in digital communication systems
• Parallel-to-serial data conversion circuits
• Address decoding logic in microprocessor interfaces

Procurement Notes

Verify the package designation 'NS' corresponds to the 16-pin SOP variant when sourcing. Confirm RoHS compliance status via the manufacturer's current documentation. Ensure the ordering suffix matches the required reel or cut tape specifications for automated assembly processes.

Selection Notes

Select this component for designs requiring two independent 4-to-1 multiplexing functions within a single integrated circuit. The HC series offers CMOS compatibility with standard TTL load driving capabilities. Consider the specific voltage requirements of the application to ensure operation within the 2 V to 6 V recommended range.

Part Context

This part belongs to the SNx4HC153 family of dual data selectors. It is functionally compatible with other 74HC153 variants from different manufacturers that adhere to the same pinout and logical specifications. The device is designed for general-purpose digital logic applications requiring efficient data selection and routing.

FAQ

How are the address inputs managed between the two channels?

Both channels share the same address select inputs (A and B), allowing simultaneous selection of data sources for both multiplexers.

What is the effect of a high level on the strobe input?

A high level at the strobe terminal forces the respective output low, effectively disabling that channel.
