74ACT11623DW

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74ACT11623DW is an octal bus transceiver featuring dual independent enable inputs (GBA and GAB) for asynchronous two-way communication between data buses. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL-compatible input levels. The device utilizes EPIC CMOS technology with center-pin VCC and GND configurations to minimize high-speed switching noise. It provides flow-through architecture optimized for PCB layout and includes local bus-latch capability when both enables are active simultaneously.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual-enable configuration allows flexible timing control for bidirectional data transmission or simultaneous bus isolation.
• Local bus-latch capability stores data by enabling both control inputs, reinforcing inputs in a transceiver configuration.
• Center-pin VCC and GND configurations minimize high-speed switching noise during operation.
• Flow-through architecture optimizes printed circuit board layout efficiency.

• Bidirectional data transmission systems
• Bus isolation applications requiring flexible timing control

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current package option addendum to confirm lead finish and moisture sensitivity level. Ensure the selected variant matches the required packaging quantity, such as tube or reel options. Confirm RoHS compliance status and environmental classification prior to finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring independent control over data direction between two 8-bit buses. The dual-enable feature offers greater flexibility compared to single-enable transceivers. Verify that the operating temperature range meets system requirements and that the supply voltage remains within the specified limits for reliable performance.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device function as a latch?

When both enable inputs (GBA and GAB) are activated simultaneously, the device reinforces its inputs, causing both sets of bus lines to remain at their last states effectively acting as a latch.

What is the purpose of the center-pin VCC and GND configuration?

The center-pin configuration is designed to minimize high-speed switching noise generated during device operation.
