Z8622812PSG

Overview

The Z8622812PSG is a dedicated Line 21 decoder manufactured by ZiLOG, designed for encoding, decoding, multiplexing, and demultiplexing functions. It operates within a supply voltage range of 4.75 V to 5.25 V and supports through-hole installation in a DIP-18 package. The component functions reliably across an operating temperature range from 0°C to +70°C. Classified under Logic ICs within the Z86228 series, this device integrates specific logic capabilities required for standard signal processing applications without requiring external microcontroller intervention.

Feature Summary

• Integrated Line 21 decoding capability for closed captioning data extraction
• Dedicated encoder, decoder, multiplexer, and demultiplexer functionality
• Through-hole mounting compatibility via standard DIP-18 packaging

Applications

• Television sets requiring Line 21 closed captioning support
• Video recording equipment with caption overlay features
• Broadcast monitoring systems utilizing Line 21 data streams

Procurement Notes

Verify RoHS compliance status directly with the manufacturer or authorized distributors before procurement, as documentation indicates detailed requirements. Confirm the DIP-18 package availability and ensure the supplier provides valid traceability documents. Check for any specific environmental certifications required for your region. Validate that the component meets the specified voltage and temperature operational limits for your intended design environment.

Selection Notes

Select this component when a dedicated hardware solution for Line 21 decoding is required rather than software-based processing. Ensure the design accommodates the 4.75 V to 5.25 V power supply constraints. Verify that the DIP-18 through-hole form factor aligns with the PCB layout and assembly processes. Consider the commercial availability status, as legacy logic components may have limited production runs compared to modern integrated solutions.

Part Context

This part belongs to the ZiLOG Z86228 series, which focuses on specialized logic functions for video signal processing. Unlike the Z86E08 or Z86E33 microcontrollers found in similar catalogs, this device is a fixed-function logic IC rather than a programmable MCU. It serves a niche role in analog-to-digital video interface standards, specifically handling the insertion and extraction of data within the vertical blanking interval of NTSC signals.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineering teams should consult official ZiLOG obsolescence notices or contact manufacturers directly for qualified pin-compatible alternatives. Cross-referencing with generic Line 21 decoder specifications may identify functional equivalents, but direct substitution requires rigorous electrical and timing verification.
