SN74AUP1T157DCKR

Overview

The SN74AUP1T157DCKR is a low-power, single 2-input multiplexer from the Texas Instruments SN74AUP1T series. It operates with input voltages of 1.8 V, 2.5 V, or 3.3 V and provides a 3.3 V CMOS output. The device utilizes two separate configurable power-supply rails to facilitate voltage level translation. Key electrical parameters include a maximum supply voltage of 3.6 V, a minimum supply voltage of 2.3 V, and a propagation delay of 5.1 ns. It functions as a non-inverting buffer multiplexer within an operating temperature range of -40°C to +85°C.

Feature Summary

• Single 2-input multiplexer configuration for selecting data from inputs A and B under common control
• Non-inverting auto-bidirectional translation capability using separate configurable power-supply rails
• Low-power design optimized for 1.8 V, 2.5 V, and 3.3 V input levels with 3.3 V CMOS output

Applications

• Voltage level translation between different logic families
• Data selection in embedded systems requiring low power consumption
• Bidirectional bus interfacing applications

Procurement Notes

Verify the specific ordering suffix 'DCKR' corresponds to the SC-70-6 package and tape-and-reel delivery format. Confirm that the component meets RoHS compliance requirements as indicated by the manufacturer's documentation. Ensure the procurement source provides valid traceability for the Texas Instruments manufacturing lot. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when a single-channel, non-inverting multiplexer is required for low-voltage applications. It is suitable for designs needing interface between 1.8 V, 2.5 V, and 3.3 V domains. Consider the SC-70-6 package size for space-constrained PCB layouts. Verify that the 5.1 ns propagation delay meets the timing requirements of the target system clock speeds.

Part Context

This part belongs to the SN74AUP1T family of low-power single-bit translators and multiplexers. It shares functional similarities with the SN74AUP1T158 but differs in inversion characteristics. The device is designed for portable and battery-operated applications due to its low power consumption. It complements other AUP series components for comprehensive digital signal management solutions.

Replacement Considerations

The SN74AUP1T157DCKT is a compatible alternative offering the same functionality in a TSSOP package. For surface-mount applications requiring a smaller footprint, the SC-70-6 package variant is preferred. Ensure pinout compatibility when substituting with other single 2-input multiplexers from the AUP series.
