74ACT16540DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT16540DLR is a 16-bit bus transceiver manufactured by Texas Instruments, belonging to the 74ACT logic family. It features two independent circuits with three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device provides high drive capability with output currents of ±24 mA and exhibits a propagation delay of approximately 11.6 ns at 5 V. Designed for surface-mount applications, it is housed in a 48-pin SSOP package and supports an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transfer between two buses using 16-bit wide channels
• Features three-state outputs that isolate the device when disabled
• Compatible with TTL input levels and CMOS output levels

Buffers, Drivers, Receivers, Transceivers Applications

• High-performance register banks
• Memory-to-memory transfers
• Bus-oriented architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm the manufacturer designation as Texas Instruments to ensure compatibility with existing design specifications. Check RoHS compliance status against current environmental regulations before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 16-bit width with registered or unregistered buffering capabilities. Ensure the system voltage aligns with the 4.5 V to 5.5 V operational range. Consider the SSOP-48 package dimensions for PCB layout constraints compared to alternative packages like DGGR.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT series of advanced CMOS logic devices, offering performance comparable to low-power Schottky TTL but with lower power consumption. The 16540 variant specifically functions as a non-inverting bus transceiver, distinct from registered variants like the 16543 which include internal latching mechanisms.
