74ACT16863DLR

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74ACT16863DLR is an 18-bit noninverting bus transceiver with 3-state outputs, designed for asynchronous communication between data buses. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. The device features TTL-voltage compatible inputs and can function as two 9-bit transceivers or one 18-bit unit. Key electrical parameters include a high-level output current of -24 mA and a low-level output current of 24 mA. Propagation delays are specified at 12.1 ns maximum (tPHL) and 11.1 ns maximum (tPLH) at 5 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest Package Option Addendum to confirm lead finish and environmental classification. Ensure the DL package variant matches the required pin spacing and thermal dissipation characteristics for the target application board design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring wide-bus data transfer with minimal propagation delay. The distributed power and ground pins make it suitable for high-density layouts where switching noise reduction is critical. Verify that input voltage levels remain within the specified TTL-compatible thresholds for reliable operation.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Widebus family of logic ICs, offering double the I/O pin count of standard small-outline packages in the same footprint. It utilizes the EPIC process technology to deliver enhanced performance compared to earlier generations of similar bus transceivers.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check the datasheet for direct pin-compatible alternatives within the 74ACT series. Verify that any substitute maintains the same 56-pin SSOP package dimensions and electrical specifications for seamless integration.
