Fairchild 74LCX162244 Data Handbook

Summary

The LCX162244 is a dedicated low-voltage, 16-bit non-inverting buffer and line driver engineered for reliable data transfer in modern digital systems (suitable for 2.5V or 3.3V applications). Key features include integrated 26Ω resistors to minimize noise and overshoot on bus lines, making it ideal for memory address drivers, clock outputs, and general bus transceiving. This manual provides comprehensive details on its electrical specifications, full operating range, pin assignments across various packages (including BGA, SSOP, and TSSOP), and technical application guidelines necessary for system designers building high-speed peripheral interfaces.

Frequently Asked Questions

What is the recommended operating voltage range for optimal performance?

The device operates best when supplied with a stable low voltage between 2.5V and 3.6V.

How does the output reduce noise or signal overshoot?

It uses patented series resistors (26: nominal) to minimize overshoot and undershoot, reducing EMI/noise in signals.

What condition turns the outputs into a high impedance state?

The outputs enter high impedance mode when the Output Enable (OE) pin is set LOW.

Can this device interface with higher voltage signaling levels?

Yes, it is designed for low voltages but has capability of interfacing to 5V signal environments.
