SN74ABT5403DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT5403DWR is a 12-bit line and memory driver featuring three-state outputs, manufactured by Texas Instruments. It utilizes EPIC-IIB BiCMOS technology for reduced power dissipation. The device 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. Outputs are designed to source or sink up to 12 mA and include equivalent 25-ohm series resistors. Propagation delays typically range from 1.5 ns to 6.9 ns at VCC = 5 V with CL = 50 pF.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DWR' corresponds to the SOIC-28 package and tape-and-reel quantity of 1000 units. Confirm that the RoHS status and lead finish match project requirements. Ensure the component meets the specified industrial temperature range limits before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 12-bit data buffering with high-density integration. The internal series resistors simplify layout by reducing EMI. Verify that the 12 mA drive capability aligns with load requirements. Consider the dual enable inputs for complex bus arbitration logic compared to single-enable alternatives.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle the high-impedance state during power-up?

To ensure the high-impedance state during power-up or power-down, the OE input should be tied to VCC through a pullup resistor. The minimum resistor value is determined by the current-sinking capability of the driver.

What is the function of the dual output enable inputs?

The 3-state control gate consists of two active-low inputs (OE1 and OE2) acting as a two-input AND gate. If either OE1 or OE2 is high, all 12 outputs enter the high-impedance state.
