74ACT11245PWE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT11245PWE4 is an octal bus transceiver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports bidirectional data transmission between two buses based on the direction-control input level. The device features TTL-voltage compatible inputs, flow-through architecture for optimized PCB layout, and center-pin VCC and GND configurations to minimize high-speed switching noise. It utilizes EPIC (Enhanced-Performance Implanted CMOS) technology and provides typical latch-up immunity of 500 mA at 125°C. The component is characterized for operation from -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the datasheet, as the PW designation indicates a Thin Shrink Small-Outline Package. Confirm RoHS compliance status and moisture sensitivity level ratings prior to ordering. Ensure design compatibility with the specified 4.5 V to 5.5 V supply voltage range and operating temperature limits of -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when asynchronous bidirectional data transfer between 5 V logic buses is required. The device is suitable for designs needing TTL-compatible inputs and minimized switching noise through its internal power pin arrangement. Verify that the application environment remains within the specified -40°C to 85°C operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT series of logic integrated circuits produced by Texas Instruments. It functions as an octal bus transceiver designed for general-purpose digital systems. The device is distinct from other variants in the family by its specific package configuration and electrical characteristics tailored for 5 V operation.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for equivalent parts such as the SN74ACT11245DWR or SN74ACT11245DBR if different packaging is required. Verify functional compatibility regarding pinout and electrical specifications before substitution.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the output-enable input affect the device?

When the output-enable input is high, the device disables the outputs, effectively isolating the buses from each other regardless of the direction-control signal state.

What determines the direction of data transmission?

The direction of data transmission is determined by the logic level at the direction-control input. A low level directs data from the B bus to the A bus, while a high level directs data from the A bus to the B bus.
