SN74HC251PWT

Overview

The SN74HC251PWT is a data selector/multiplexer featuring full binary decoding to select one of eight data sources. It includes strobe-controlled complementary three-state outputs for bus-organized systems. The device operates within a wide voltage range of 2 V to 6 V and consumes low power, with a maximum ICC of 80 μA. Typical propagation delay is 9 ns, and it provides ±6 mA output drive at 5 V. It utilizes a TSSOP package with 16 pins.

Feature Summary

• Features full binary decoding to select one of eight data sources
• Provides strobe-controlled complementary three-state outputs
• Supports parallel-to-serial conversion functions
• Interfaces directly with system buses or drives LSTTL loads

Applications

• Data source selection in digital circuits
• Bus-oriented system interfacing
• Parallel-to-serial data conversion

Procurement Notes

Verify the specific ordering suffix 'W' corresponds to the TSSOP package variant. Confirm RoHS compliance status and lead finish details via the manufacturer's current orderable addendum. Ensure the component status is checked as production data may change without notice.

Selection Notes

Select this component when an 8-input multiplexer with three-state outputs is required. It serves as the three-state version of the standard HC151 logic family. Consider the operating temperature range and supply voltage requirements relative to the system design constraints.

Part Context

This part belongs to the Texas Instruments SNx4HC251 series of high-speed CMOS logic devices. The series encompasses various packages including SOIC, SSOP, PDIP, and TSSOP. The SN74HC251PWT specifically denotes the catalog version housed in a TSSOP-16 package.

Replacement Considerations

SN74HC251PWR is listed as an active alternative in the same TSSOP package.
