74ACT16245DLRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT16245DLRG4 is a 16-bit bus transceiver manufactured by Texas Instruments, housed in a 48-pin SSOP package. It features non-inverting logic with three-state outputs designed to drive bus lines directly. The device inputs are TTL-voltage compatible, while the outputs provide CMOS-level signaling. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 9.5 ns. The component functions as two independent 8-bit circuits and is rated for an operating temperature range from -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides 16-bit bidirectional data transmission capability through dual 8-bit configurations
• Features TTL-compatible input levels ensuring direct interface with standard logic families
• Utilizes three-state outputs to facilitate direct connection to system bus architectures

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus interfaces requiring wide word processing
• Memory mapping systems utilizing 16-bit data paths
• Control logic circuits interfacing TTL sources with CMOS loads

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm compliance with RoHS directives and lead-free manufacturing standards. Ensure the SSOP-48 package dimensions match the target PCB footprint requirements. Confirm that the 5V supply voltage aligns with the system power rails before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit width is required with TTL input compatibility at 5V operation. It serves as a suitable alternative to lower-speed variants like the 74HC series or different voltage domains such as the LVTH series. Consider the thermal performance of the SSOP package if high ambient temperatures near the upper limit are expected.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments Widebus family of logic ICs. It is functionally related to other 16-bit transceivers in the ACT series, sharing similar pinouts but differing in speed and drive strength characteristics compared to ALVC or AVC counterparts.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ACT16245DLR is a direct functional equivalent without the G4 suffix. Other 16-bit ACT transceivers may serve as substitutes if timing parameters allow.
