PI74ALVCH162601A

Universal Bus Functions Overview

The PI74ALVCH162601 is an 18-bit universal bus transceiver manufactured by Diodes Incorporated using advanced 0.5 micron CMOS technology. It features D-type latches and flip-flops with 3-state outputs, supporting transparent, latched, and clocked data flow modes. The device operates within a supply voltage range of 2.3V to 3.6V and supports industrial temperatures from -40°C to +85°C. It includes Bus Hold functionality to retain input states during high-impedance conditions.

Universal Bus Functions Feature Summary

• Supports transparent, latched, and clocked data flow modes via dedicated control inputs
• Includes Bus Hold circuitry to maintain the last active bus state during high-impedance periods
• Features series resistors on B-port outputs to reduce signal overshoot and undershoot

Universal Bus Functions Applications

• High-speed data transfer between microprocessors and memory modules
• Clock distribution networks requiring precise timing control
• Bidirectional data buffering in complex digital logic systems

Universal Bus Functions Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete or superseded. Confirm package availability matches design requirements, specifically the 56-pin TSSOP or SSOP options. Ensure all unused control inputs are properly terminated to prevent floating states during operation.

Universal Bus Functions Selection Notes

Select this component for applications requiring 18-bit bidirectional data transfer with flexible mode control. Consider the specific power supply constraints of 2.3V to 3.6V when designing the system. Evaluate the need for Bus Hold functionality to simplify external resistor requirements on high-impedance buses.

Universal Bus Functions Part Context

This device belongs to the PI74ALVCH series of logic circuits produced by Pericom Semiconductor Corporation, now part of Diodes Incorporated. The series utilizes advanced CMOS technology to achieve industry-leading speed performance for low-voltage digital applications.

Universal Bus Functions Replacement Considerations

Check for direct pin-compatible alternatives from manufacturers such as Texas Instruments or Nexperia if the PI74ALVCH162601 is unavailable. Verify that any substitute maintains the same 18-bit configuration and 3-state output characteristics.
