Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering code matches the required package type, as the TTR suffix indicates Tape and Reel packaging in the TSSOP-16 format. Confirm that the intended application environment falls within the specified operating temperature range of -55°C to +125°C. Ensure supply voltage requirements align with the 2V to 6V operational limits defined in the datasheet before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad 2-input multiplexer with high-speed performance and low power consumption is required. The 74AC157TTR is suitable for designs needing operation across a wide voltage range from 2V to 6V. Consider its 2kV ESD immunity and improved latch-up immunity for robust system reliability. Verify pin compatibility with existing 74 series 157 layouts if migrating from older technologies.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AC157 family of quad 2-channel multiplexers manufactured by STMicroelectronics. It utilizes sub-micron silicon gate and double-layer metal wiring C2MOS technology. The device is functionally compatible with standard 74 series 157 components but offers enhanced speed and lower power characteristics typical of the AC logic family.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct replacements include other manufacturers' 74AC157 variants or 74HC157 equivalents, provided voltage levels and speed requirements are met. Verify pinout compatibility and ensure the substitute supports the required 2V to 6V operating range.
