PI74ALVCH16260A

Latches Overview

The PI74ALVCH16260A is a 12-bit to 24-bit multiplexed D-type latch featuring 3-state outputs, designed for low voltage operation with VCC ranging from 2.3V to 3.6V. It includes hysteresis on all inputs and typical VOLP (Output Ground Bounce) less than 0.8V at VCC = 3.3V and TA = 25°C. The device supports industrial operation temperatures from –40°C to +85°C and is available in a 56-pin 240 mil wide plastic TSSOP package.

Latches Feature Summary

• Multiplexes two separate datapaths onto or demultiplexes from a single data path using internal storage latches
• Features active bus-hold circuitry to retain the last active bus state during 3-State conditions without external pullup resistors
• Includes three 12-bit I/O ports controlled by dedicated output-enable and latch-enable inputs

Latches Applications

• Microprocessor address and data information multiplexing
• Bus-interface applications requiring data path selection
• Memory-interleaving systems

Latches Procurement Notes

Verify that the component matches the specific Pericom Semiconductor Corporation manufacturing origin associated with Diodes Incorporated. Confirm the package code 'A' corresponds to the 56-pin 240 mil wide plastic TSSOP form factor. Ensure the operating temperature range meets the required industrial specifications of –40°C to +85°C before integration into the design.

Latches Selection Notes

Select this component when designing circuits that require multiplexing two distinct 12-bit data paths into a single 24-bit interface or vice versa. It is suitable for low voltage logic families operating between 2.3V and 3.6V. Consider its active bus-hold feature if minimizing external passive components is a priority for the board layout.

Latches Part Context

This part belongs to the ALVCH logic family, characterized by advanced low-voltage CMOS technology. It functions as a specialized latch and transceiver hybrid, bridging the gap between standard logic gates and complex memory controllers. The device integrates control logic for bank switching and data storage directly within the latch structure.
