Z53C8003PSC

Overview

The Z53C8003PSC is a SCSI interface integrated circuit manufactured by Zilog, belonging to the Z53C80 series. It functions as an 8-terminated SCSI terminator designed for signal integrity in SCSI bus architectures. The device utilizes CMOS technology and operates within a supply voltage range of 4.75 V to 5.25 V. It supports data transfer rates up to 3 MB/sec. The component is housed in a 48-pin Dual In-line Package (DIP) with a standard pin spacing of 0.600 inches (15.24 mm). It is rated for operation at temperatures between 0°C and +70°C. The part status is officially listed as End-of-Life.

Feature Summary

Integrated 8-termination capability for SCSI bus signal termination
CMOS construction ensuring compatibility with standard logic levels
Supports SCSI I data transfer speeds up to 3 MB/sec

Applications

Terminating SCSI buses in legacy computer systems
Signal integrity management in SCSI peripheral connections
Maintenance of vintage storage subsystems requiring SCSI I compliance

Procurement Notes

This component is confirmed as End-of-Life by the manufacturer. Availability is restricted to surplus or secondary market channels. Verify RoHS compliance status carefully, as datasheets indicate non-compliance for this specific package variant. Ensure the 48-DIP package matches the target PCB footprint before acquisition.

Selection Notes

Select this part only if a 48-pin DIP form factor is required for through-hole mounting. Compare against the Z53C8003VSG for surface-mount PLCC alternatives. Confirm that the 3 MB/sec speed rating meets system requirements. Note that this is a passive terminator IC, not a controller.

Part Context

Part of the Z53C80 family of SCSI interface components. Related variants include Z53C8003FSC (QFP-44) and Z53C8003VSG (PLCC-44). All share the same core SCSI termination functionality but differ in package type and mounting style.

Replacement Considerations

No direct active substitutes are publicly documented. Consider Z53C8003VSG or Z53C8003FSC if package adaptation is feasible. Legacy SCSI terminators may require level-shifting verification.
