PI74ALVCH16501A

Universal Bus Functions Overview

The PI74ALVCH16501A is an 18-bit universal bus transceiver manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.3V to 3.6V and features 3-state outputs. The device utilizes advanced 0.5 micron CMOS technology for high-speed performance. It includes latched enable, clock, and output enable inputs to control data flow direction between A and B buses. The component supports industrial operating temperatures from -40°C to +85°C and is available in 48-pin TSSOP or SSOP packages.

Universal Bus Functions Feature Summary

• Supports bidirectional data transfer with independent latch and clock controls for each direction
• Incorporates active bus-hold circuitry to maintain valid logic levels on floating inputs
• Provides low output ground bounce and undershoot characteristics during switching
• Ensures high-impedance states during power-up or power-down sequences

Universal Bus Functions Applications

• High-speed data bus interfaces requiring registered buffering
• Mixed-signal systems utilizing low-voltage CMOS logic families
• Memory bus architectures needing controlled data latching and tri-state isolation
• Industrial electronic equipment operating across extended temperature ranges

Universal Bus Functions Procurement Notes

Verify the specific package suffix against the datasheet requirements, as the 'A' designation corresponds to the 48-pin 240 mil wide plastic TSSOP form factor. Confirm that the intended application environment remains within the specified -40°C to +85°C operational temperature limits. Ensure proper termination of unused control inputs to prevent floating states, as indicated in the product documentation.

Universal Bus Functions Selection Notes

Select this component when an 18-bit width is required for universal bus applications. The device is suitable for designs necessitating separate clocking and latching mechanisms for distinct data directions. Consider the 2.3V to 3.6V supply constraint and the availability of 48-pin surface-mount packages. Verify compatibility with existing system timing requirements regarding propagation delays and setup times.
