PI74AVC164245A

Translators, Level Shifters Overview

The PI74AVC164245A is a 16-bit (dual-octal) noninverting bus transceiver manufactured by Diodes Incorporated. It features two separate supply rails: Port B (VCCB) operates at 3.3V, while Port A (VCCA) supports 1.8V to 2.5V. This configuration enables voltage translation between 1.8-2.5V and 3.3V environments. The device utilizes advanced 0.35 micron CMOS technology for high performance. It provides asynchronous communication between data buses with 3-state outputs. Industrial operation is supported from -40°C to +85°C.

Translators, Level Shifters Procurement Notes

Verify the package suffix matches the required form factor: 'A' indicates 48-pin TSSOP, 'K' indicates 48-pin TVSOP, and 'V' indicates 48-pin SSOP. Confirm that the specific ordering suffix aligns with the physical footprint requirements of the target PCB design. Ensure compatibility with the specified industrial temperature range of -40°C to +85°C for the intended operating environment.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic circuits operating at 1.8V or 2.5V with those operating at 3.3V. The device is suitable for applications requiring bidirectional data flow controlled by separate DIR inputs for each octal section. Consider the available package options (TSSOP, TVSOP, SSOP) based on board space constraints. Ensure pull-up resistors are used on the OE input to maintain high impedance states during power transitions.

Translators, Level Shifters FAQ

How does the device handle power-up and power-down conditions?

To ensure a high impedance state during power transitions, the output-enable (OE) input must be tied to VCC through a pull-up resistor.

What is the function of the DIR inputs?

The DIR inputs control the direction of data transmission. Setting DIR high allows transmission from Port A to Port B, while setting it low allows transmission from Port B to Port A.
