GAL22LV10ZD-15QJ

Programmable Logic Device Pld Overview

The GAL22LV10ZD-15QJ is a Simple Programmable Logic Device (SPLD) from the GAL22V10 family, manufactured by Lattice Semiconductor. It utilizes E2CMOS technology to provide high performance with low power consumption. The device features 22 input lines and 10 output lines, organized into 10 macrocells. It operates within a voltage range of 4.75 V to 5.25 V and supports a maximum propagation delay of 15 ns. The component is housed in a 28-pin Plastic Leaded Chip Carrier (PLCC) package designed for surface-mount applications.

Programmable Logic Device Pld Feature Summary

• E2CMOS technology enabling operation at 5V with reduced power dissipation compared to bipolar equivalents
• High-speed logic performance with a maximum propagation delay of 15 ns
• Flexible I/O configuration with 22 inputs and 10 outputs across 10 macrocells
• Surface-mount 28-PLCC package suitable for automated assembly processes

Programmable Logic Device Pld Applications

• Address decoding and memory interface logic in embedded systems
• Signal buffering and protocol conversion between digital components
• General-purpose combinatorial or registered logic implementation
• Replacement for legacy GAL devices in existing hardware designs

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'ZD' against official Lattice documentation to confirm it denotes zero-power or specific variant characteristics, as standard datasheets often list 'GAL22V10D'. Confirm RoHS compliance status, as older GAL variants may not meet current environmental standards. Check for End-of-Life (EOL) notifications, as this family has been subject to discontinuation notices in previous years. Ensure the supplier provides valid traceability for the PLCC-28 package.

Programmable Logic Device Pld Selection Notes

Select this component when a 5V SPLD with 22 inputs and 10 outputs is required. The 15 ns speed grade is suitable for moderate-frequency digital logic. Compare against the GAL22V10D series if the 'Z' (Zero Power) feature is critical for standby current reduction. Ensure the design accommodates the 28-PLCC footprint. Verify that the application voltage remains within the 4.75V to 5.25V range.
