CLVC257AQPWRG4Q1

Overview

The CLVC257AQPWRG4Q1 is an automotive-grade quadruple 2-line to 1-line data selector/multiplexer with 3-state outputs. It operates from a supply voltage of 2V to 3.6V and accepts input voltages up to 5.5V. The device features a maximum propagation delay of 4.6ns at 3.3V. Electrostatic discharge protection exceeds 2000V per MIL-STD-883, method 3015. It is housed in a 16-pin TSSOP (PW) package.

Feature Summary

Procurement Notes

Verify the specific ordering suffix G4Q1 against the latest Texas Instruments Package Option Addendum to confirm active production status and material compliance. Ensure the selected package type matches the design requirements, as this part number specifically denotes the TSSOP variant. Cross-reference the manufacturer's official documentation for any recent changes to lead finish or moisture sensitivity levels before finalizing procurement plans.

Selection Notes

Select this component when designing mixed 3.3V/5V system environments requiring signal translation and multiplexing. The high input voltage tolerance allows direct interfacing with 5V devices without additional level shifting circuitry. Consider the 3-state output capability to prevent loading on data lines when the output-enable input is at a high logic level during system operation.

Part Context

This device belongs to the SN74LVC257A-Q1 family of quadruple 2-line to 1-line data selectors/multiplexers. It is designed for automotive applications and offers robust performance characteristics suitable for demanding electronic systems. The LVC series provides low voltage CMOS technology optimized for high-speed digital signal routing.

FAQ

How does the device handle unused inputs?

Unused inputs must not be left floating. They should be connected to a high or low bias, typically tied to VCC or GND, to prevent undefined operational states.

What is the recommended power supply bypassing strategy?

Each VCC terminal must have a good bypass capacitor. A 0.1-μF capacitor is recommended for single-supply devices, placed as close to the power terminal as possible.
