74AVCH1T45DCKRE4

Overview

The SN74AVCH1T45DCKRE4 is a single-bit dual-supply bus transceiver from the Texas Instruments 74AVCH series. It operates with supply voltages ranging from 1.2 V to 3.6 V on both ports A and B, enabling configurable voltage translation between different logic domains. The device features three-state outputs and supports bidirectional data flow. It is housed in a 6-pin SC-70 package and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Configurable voltage translation between two independent power supply rails
• Bidirectional data transmission capability
• Three-state output configuration

Applications

• Connecting microprocessors to memory modules
• Level shifting between I/O ports and peripheral devices
• Portable equipment requiring low-voltage operation

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the SC-70 package dimensions match the design footprint requirements. Ensure the operating voltage range aligns with the target system's power rails before integration.

Selection Notes

Select this component when a single-channel bidirectional translator is required for mixed-voltage systems. The AVCH series offers faster propagation delays compared to standard AVC variants. Verify that the SC-70 package size fits within the available PCB area constraints.

Part Context

This part belongs to the 74AVCH family of high-speed bus transceivers designed for low-voltage applications. It serves as a bridge between different voltage domains, ensuring signal integrity during level translation. The device is part of Texas Instruments' broader portfolio of logic ICs focused on portable and battery-powered electronics.

Replacement Considerations

SN74AVC1T45DCKRE4 is a verified substitute within the same product family.
