74LV245PW,112

Overview

The 74LV245PW,112 is an octal bus transceiver manufactured by Nexperia USA Inc. It features 3-state outputs and operates within a wide supply voltage range of 1.0 V to 5.5 V. The device accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V. It includes output enable (OE) and send/receive (DIR) controls for direction management. Inputs are equipped with clamp diodes to interface with voltages exceeding VCC using current limiting resistors. The component complies with JEDEC standards for various low-voltage applications and offers ESD protection exceeding 2000 V HBM.

Feature Summary

• Octal bidirectional data transmission with 3-state outputs
• Direction control via dedicated OE and DIR inputs
• Input clamp diodes allow interfacing with voltages higher than VCC
• Compliance with multiple JEDEC low-voltage standards

Applications

• Low voltage memory mapping
• Clock driving and buffering
• Bus-oriented communications

Procurement Notes

Verify the specific ordering suffix and package variant against the official Nexperia datasheet before procurement. Confirm that the intended application environment aligns with the specified operating temperature range and electrical characteristics. Ensure compatibility with existing system voltage levels, particularly regarding the TTL input level acceptance at lower supply voltages. Check for any recent lifecycle status updates or end-of-life notifications from the manufacturer.

Selection Notes

Select this component when an 8-bit bidirectional transceiver is required for systems operating between 1.0 V and 5.5 V. It is suitable for applications needing TTL-compatible inputs at 2.7 V to 3.6 V supplies. Consider its latch-up performance and ESD ratings for robust industrial environments. Evaluate the DIP-20 through-hole package suitability if PCB space allows and surface-mount options are not mandatory.
