SN74AVCAH164245G

Translators, Level Shifters Overview

The SN74AVCAH164245 is a 16-bit dual-supply bus transceiver with configurable voltage translation and tri-state outputs. It supports VCCA and VCCB supply voltages ranging from 1.4 V to 3.6 V, enabling universal bidirectional translation between 1.5-V, 1.8-V, 2.5-V, and 3.3-V nodes. The device features DOC circuitry for dynamic output impedance control, active bus-hold inputs, and IOFF support for partial-power-down mode. Control pins are referenced to VCCA.

Translators, Level Shifters Feature Summary

DOC circuitry dynamically adjusts output impedance to reduce noise without degrading speed
Active bus-hold circuitry maintains valid logic levels on floating data inputs
IOFF circuitry disables outputs to prevent damaging backflow current during power-down
Overvoltage-tolerant inputs and outputs facilitate mixed-voltage-mode communications

Translators, Level Shifters Applications

Asynchronous communication between data buses
Universal low-voltage bidirectional translation between multiple voltage nodes
Partial-power-down applications requiring high-impedance isolation

Translators, Level Shifters Procurement Notes

Verify the specific package variant (TSSOP DGG, TVSOP DGV, or VFBGA GQL) matches the design footprint. Confirm that the ordering suffix corresponds to the required tape-and-reel quantity of 2000 units. Ensure the selected part number aligns with the intended operating temperature range of -40 °C to +85 °C.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems with differing supply rails within the 1.4-V to 3.6-V range. The dual-supply architecture allows independent configuration of Port A and Port B. Consider the DOC feature for signal integrity in high-speed asynchronous transfers where standard drive strength may cause excessive ringing.

Translators, Level Shifters Part Context

This device belongs to the Texas Instruments Widebus family of logic ICs. It is designed specifically for asynchronous data transmission across different voltage domains. The architecture utilizes two separate configurable power-supply rails to manage the translation process efficiently.
