TC7WH157FU,LJ(CT

Overview

The TC7WH157FU,LJ(CT is a Toshiba L-MOS Logic (VHS) 2-channel multiplexer housed in an SSOP-8 package. It operates within a supply voltage range of 2 V to 5.5 V and supports surface mount installation. The device features a common select input and strobe control, routing either A or B inputs to the Y output based on logic states. Propagation delays are specified at 13.2 ns at 3.3 V and 8.4 ns at 5 V under standard load conditions. Operating temperatures span from -40°C to +85°C with a maximum power dissipation of 300 mW.

Feature Summary

• Features high-speed CMOS technology for operation comparable to Bipolar Schottky TTL while maintaining low power consumption.
• Includes input protection circuits allowing 0 to 7 V tolerance regardless of supply voltage, facilitating safe interfacing between 5 V and 3 V systems.
• Provides balanced propagation delays where tpLH approximately equals tpHL.

Applications

• Interfacing 5 V to 3 V systems
• Battery backup system integration
• General electronics applications including computer and office equipment

Procurement Notes

Verify that the specific ordering suffix matches the required package variant, as the FU designation corresponds to the SSOP-8-P-0.65 form factor. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to procurement. Ensure the component meets the intended environmental operating temperature range of -40°C to +85°C for the specific application environment.

Selection Notes

Select this component when a single-channel 2-to-1 multiplexing function is required within a compact SSOP-8 footprint. It is suitable for designs needing voltage translation capabilities between 3 V and 5 V domains without external level shifters. Consider the quiescent current specifications if battery life is a critical design constraint.

Part Context

This part belongs to the TC7WH series of advanced high-speed CMOS digital integrated circuits manufactured by Toshiba Semiconductor and Storage. The series utilizes silicon gate CMOS technology to achieve performance levels similar to Bipolar Schottky TTL. The TC7WH157 specifically functions as a 2-input digital multiplexer with common select and strobe inputs.
