TC74VCX157FTEL

Overview

The TC74VCX157FTEL is a low-voltage quad 2-channel multiplexer manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 1.2 V to 3.6 V, supporting systems at 1.5 V, 1.8 V, 2.5 V, or 3.3 V. The device features four independent multiplexers with common select and strobe inputs. Propagation delay ranges from 3.0 ns maximum at 3.0–3.6 V to 35.0 ns maximum at 1.2 V. Output drive capability is ±24 mA minimum at 3.0 V. Inputs and outputs are tolerant up to 3.6 V and include power-down protection. It is housed in a TSSOP-16 package.

Feature Summary

• Low-voltage operation across 1.2 V to 3.6 V supply range
• High-speed digital signal routing with minimal propagation delay
• 3.6 V tolerant inputs and outputs with power-down protection
• Wide operating temperature range extending to 125 °C

Applications

• Data routing in 1.5 V, 1.8 V, 2.5 V, or 3.3 V logic systems
• Signal selection in portable electronic devices
• Interface circuits requiring voltage level compatibility

Procurement Notes

Verify the manufacturing date against the April 2020 cutoff for the extended -40 °C to 125 °C operating temperature specification. Confirm that the TSSOP-16 package matches the design footprint requirements. Ensure input signals do not exceed the absolute maximum ratings during power-up or power-down sequences to maintain device integrity.

Selection Notes

Select this component when system architecture requires multiple data sources to be routed to a single destination under low-voltage conditions. The 3.6 V tolerance allows interfacing between different voltage domains without external level shifters. Consider the propagation delay specifications relative to the specific supply voltage being utilized in the target application circuit.

Part Context

This part belongs to the TC74VCX series of CMOS digital integrated circuits. It functions as a silicon monolithic multiplexer designed for high performance and low power dissipation. The device integrates static discharge protection on all inputs and utilizes a common select decoding mechanism to determine data path routing between A/B inputs and Y outputs.
