74ABT245PW,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABT245PW,112 is an octal bus transceiver featuring 3-state outputs and BiCMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports direct interface with TTL levels. The device provides high-speed performance with propagation delays ranging from 1.0 ns to 6.3 ns depending on the transition type. Output drive capability reaches +64 mA for low-level and -32 mA for high-level states. It includes IOFF circuitry for partial power-down applications and meets ESD protection standards exceeding 2000 V (HBM) and 1000 V (CDM).

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bidirectional bus interface with direction control pin.
• BiCMOS high speed and output drive capabilities.
• IOFF circuitry enables partial power-down mode operation.

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data transmission systems.
• Memory bus architectures requiring 3-state isolation.
• Industrial control systems interfacing with TTL logic.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix matches the required package variant, as the PW suffix denotes TSSOP20. Confirm the temperature grade corresponds to industrial specifications (-40 °C to +85 °C). Ensure compatibility with 5 V logic families before integration. Check for RoHS compliance status in current distributor listings. Validate lead times directly with authorized suppliers.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring wide output drive strength and fast switching speeds at 5 V. It is suitable for applications needing direct TTL interfacing without additional level shifting. Consider the TSSOP20 package if space constraints allow for thin shrink outlines. Evaluate thermal dissipation requirements given the high current drive capabilities during active operation.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series, which utilizes BiCMOS technology for superior speed compared to standard CMOS variants. It serves as an octal version of the 74ABT family, providing eight bits of bidirectional data transfer. The device complements other 74ABT logic gates by offering robust bus driving capabilities essential for complex digital interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ABT245D is a functional equivalent using an SO20 package instead of TSSOP20. Verify pinout compatibility and physical dimensions before substitution. Other 74ABT family members may offer similar electrical characteristics but differ in bit width or package options.
