V62/23618-01XE

Overview

The SN74AHCT245-EP is an enhanced product octal bus transceiver designed for asynchronous two-way communication between data buses. It operates from a supply voltage of 4.5 V to 5.5 V and features TTL-voltage compatible inputs with latch-up performance exceeding 250 mA per JESD 17. The device supports defense, aerospace, and medical applications through controlled baseline manufacturing, single assembly and test sites, extended product life cycles, and full product traceability. It is housed in a 20-pin TSSOP package.

Feature Summary

• Supports defense, aerospace, and medical applications via controlled baseline manufacturing
• Features TTL-voltage compatible inputs for seamless interface integration
• Provides high latch-up protection exceeding 250 mA per JESD 17 standards

Applications

• Enable or disable digital signals within system architectures
• Hold signals during controller reset sequences
• Debounce mechanical switches in input circuits

Procurement Notes

Verify the specific ordering suffix matches the required military or enhanced product specifications. Confirm that the component originates from the designated fabrication and assembly sites listed in the datasheet. Ensure the purchase order explicitly references the V62/23618-01XE designation to guarantee compliance with the controlled baseline and traceability requirements mandated for defense and aerospace use cases.

Selection Notes

Select this component when asynchronous bidirectional data transfer is required between 5-V buses. It is suitable for systems demanding high reliability and strict environmental controls. The TTL-compatible input thresholds allow direct interfacing with legacy logic families. Consider the thermal resistance values and operating temperature range of -55°C to 125°C for harsh environment deployments.

Part Context

This part belongs to the SN74AHCT245 family of octal bus transceivers. The 'EP' suffix denotes Enhanced Product status, indicating adherence to stricter manufacturing controls compared to standard catalog parts. It serves as a bridge for data buses, offering three-state outputs and direction control. The V62/23618-01XE identifier specifies the qualified version for government and industrial contracts requiring provenance verification.

Replacement Considerations

Qualified substitutes include SN74AHCT245MPWREP for general production needs. For automotive applications, consider SN74AHCT245-Q1. Military-grade requirements may be met by SN54AHCT245. Verify pinout compatibility and electrical characteristics before substitution.
