TC74VHC157FTEL

Overview

The TC74VHC157FTEL is a quad 2-channel multiplexer fabricated with silicon gate C2MOS technology. It operates within a supply voltage range of 2.0 V to 5.5 V and supports input voltages up to 5.5 V regardless of the supply level. The device features high-speed operation with a typical propagation delay of 4.1 ns at 5 V, low quiescent current of 4 μA maximum, and balanced propagation delays. It includes power-down protection on all inputs and is housed in a 16-TSSOP package.

Feature Summary

• High-speed digital signal routing with balanced propagation delays
• Input protection circuits allowing 5.5 V tolerance independent of supply voltage
• Power-down protection provided on all inputs to prevent device destruction
• Low noise performance with quiet output specifications

Applications

• Interfacing 5 V systems to 3 V systems
• Two-supply systems such as battery backup configurations
• General electronics applications including computers and office equipment

Procurement Notes

Verify that the specific ordering suffix corresponds to the TSSOP-16B package type required for your design. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation before finalizing procurement. Ensure the component meets the intended operating temperature range requirements for your specific application environment.

Selection Notes

Select this component when high-speed multiplexing is required alongside CMOS low-power dissipation characteristics. It serves as a functional equivalent to the 74ALS157 series while offering improved speed and lower power consumption. Consider its wide operating voltage range and input voltage tolerance when designing mixed-voltage logic interfaces.
