74ACT16470DL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT16470DL is a 16-bit registered bus transceiver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. The device exhibits a propagation delay of 9.8 ns at 5 V with 50 pF load. It provides high drive capability with low-level output current of 24 mA and high-level output current of -24 mA. The component functions in non-inverting polarity and contains two circuits across 16 channels. It is housed in a 56-pin SSOP package and is characterized for operation between -40°C and +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DL' corresponds to the SSOP-56 package variant when sourcing. Confirm RoHS compliance status as some distributors list this part as non-compliant or legacy. Ensure the operating temperature range meets system requirements of -40°C to +85°C. Cross-reference the manufacturer number SN74ACT16470DL with the base product number 74ACT16470 to confirm functional equivalence. Check for moisture sensitivity level constraints during handling.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring 16-bit wide data paths with registered output control. It is suitable where TTL compatibility is necessary alongside CMOS performance. Consider the 56-pin SSOP footprint for PCB layout constraints. Evaluate the 9.8 ns propagation delay against system timing budgets. Compare drive strength requirements against the 24 mA output capability for load matching.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ACT logic family, which combines the speed of advanced bipolar technology with CMOS low power consumption. It is part of the broader 74ACT16xxx series of 16-bit logic components. The SN74ACT16470DL serves as a registered transceiver, distinct from unbuffered variants. It complements other Texas Instruments logic solutions for complex digital system designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ABT16470DL is a related BiCMOS variant offering faster switching speeds but may require different voltage considerations. Verify pinout compatibility before substituting with other 16-bit registered transceivers from the same manufacturer. Ensure package dimensions match the existing board layout for direct replacement.
