SN74ABTH16460DL

Specialty Logic Overview

The SN74ABTH16460DL is a 56-pin SSOP multiplexed registered transceiver from the Widebus family. It operates on a 4.5 V to 5.5 V supply with an operating temperature range of -40°C to +85°C. The device features high-drive outputs capable of -32 mA IOH and 64 mA IOL, supporting clock frequencies up to 160 MHz. Propagation delays typically range from 2 ns to 7.8 ns depending on the signal path. It includes bus-hold circuitry for data inputs and maintains a high-impedance state during power-up or power-down.

Specialty Logic Feature Summary

• Multiplexes four separate 4-bit data paths onto a single 4-bit path using dedicated select pins.
• Integrates internal storage latches and flip-flops for address and data information retention.
• Features active bus-hold circuitry on data inputs to eliminate external pullup or pulldown resistors.
• Maintains a high-impedance state during power-up and power-down sequences.

Specialty Logic Applications

• Multiplexing and demultiplexing address and data information in microprocessor applications.
• Bus-interface applications requiring multiple data path selection.
• Memory-interleaving applications.

Specialty Logic Procurement Notes

Verify the specific ordering suffix 'DL' corresponds to the SSOP-56 package configuration required for your PCB layout. Confirm that the component meets the -40°C to +85°C commercial temperature grade specifications rather than the military grade variant. Ensure design compatibility with the 4.5 V to 5.5 V supply voltage requirements before finalizing procurement.

Specialty Logic Selection Notes

Select this component when a design requires routing four distinct 4-bit data streams through a shared interface controlled by software-selectable channels. The integrated latch functionality allows for data storage without external memory components. Verify that the 56-pin SSOP footprint fits within the available board space constraints.
