CY74FCT480BTPC

Parity Generators And Checkers Overview

The CY74FCT480BTPC is a dual 8-bit parity generator/checker from the FCT logic series, housed in a 24-pin PDIP package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of -40°C to +85°C. The device features a propagation delay of 6.1 ns and provides 32-mA output sink current and 32-mA output source current. It includes Ioff circuitry for partial-power-down support and open-drain active-low parity-error outputs.

Parity Generators And Checkers Feature Summary

• Dual 8-bit parity generation and checking capabilities
• Open-drain active-low parity-error output for wired-OR expansion
• Ioff circuitry supporting partial-power-down mode operation
• Fully compatible with TTL input and output logic levels

Parity Generators And Checkers Applications

• Odd-parity systems requiring word width expansion
• Data integrity verification in digital circuits
• Partial-power-down applications utilizing Ioff functionality

Parity Generators And Checkers Procurement Notes

Verify the specific ordering suffix 'BTPC' corresponds to the 24-pin PDIP tube packaging and the 6.1 ns speed grade. Confirm RoHS compliance status and lead finish details (CU NIPDAU) against the latest manufacturer documentation before finalizing procurement specifications.

Parity Generators And Checkers Selection Notes

Select this component when dual independent 8-bit parity functions are required within a single package. Ensure the design accommodates the 32-mA drive capability and utilizes the open-drain ERROR output correctly for wired-OR connections if expanding beyond 8 bits. Verify power supply stability within the 4.75 V to 5.25 V range.

Parity Generators And Checkers Part Context

This part belongs to the Texas Instruments FCT logic family, designed for high-speed CMOS applications. It is functionally compatible with F Logic standards. The device integrates edge-rate control circuitry to improve noise characteristics and offers ESD protection exceeding JESD 22 standards for human-body, machine, and charged-device models.

Parity Generators And Checkers Replacement Considerations

CY74FCT480ATPC is a verified substitute offering a 7.5 ns speed grade in the same 24-pin PDIP package.
