PI74AVC+16268A

Universal Bus Functions Overview

The PI74AVC+16268 is a 12-bit to 24-bit registered bus exchanger featuring 3-state outputs. It operates on a single VCC supply ranging from 1.65V to 3.6V. The device provides true balanced drive currents of ±24mA at 3.3V and includes IOFF support for partial power-down operation. Inputs and outputs are tolerant up to 3.6V. All outputs incorporate a patented Dynamic Drive Control (DDC) circuit designed to reduce noise without degrading propagation delay. Industrial operating temperature ranges from -40°C to +85°C.

Universal Bus Functions Feature Summary

• Synchronous data exchange between narrow high-speed buses and wide lower-frequency buses using internal registers triggered by clock transitions.
• Patented Dynamic Drive Control (DDC) circuit integrated into all outputs to minimize signal noise while maintaining propagation speed.
• Supports partial power-down operation through IOFF functionality, ensuring safe high-impedance states during power cycles.

Universal Bus Functions Applications

• Transferring data from narrow high-speed buses to wide, lower-frequency buses
• Synchronous data exchange applications requiring registered bus interfacing
• Memory address drivers and clock drivers in low-voltage systems

Universal Bus Functions Procurement Notes

Verify the specific package variant required, as the component is available in 56-pin TSSOP (A suffix) or TVSOP (K suffix). Confirm that the design accommodates the requirement for a clock pulse and pullup resistor on OE inputs to establish proper high-impedance states during power-up sequences. Ensure unused control inputs are tied to defined logic levels to prevent floating.

Universal Bus Functions Selection Notes

Select this component when synchronous translation between 12-bit and 24-bit data paths is necessary within a single-supply environment. The device is suitable for designs requiring low-voltage operation between 1.65V and 3.6V with robust noise reduction capabilities. Consider the DDC feature for applications sensitive to electromagnetic interference where propagation delay must remain minimal.
