CY74FCT245ATPC

Overview

The CY74FCT245ATPC is an octal bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features eight non-inverting channels with three-state outputs, housed in a 20-pin PDIP package for through-hole mounting. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. It exhibits a propagation delay of 4.6 ns, with low-level output current capability of 12 mA and high-level output current of -15 mA. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides bidirectional data transmission via eight independent channels
• Features three-state outputs to facilitate direct system bus connections
• Supports TTL-compatible input and output voltage levels

Applications

• Memory map applications
• Bus-oriented architectures
• Clock drivers

Procurement Notes

Verify the specific suffix 'TPC' confirms the PDIP-20 through-hole package variant. Confirm RoHS compliance status as indicated in official documentation. Ensure the order matches the required operating temperature range and electrical specifications for the target design environment.

Selection Notes

Select this component when a through-hole octal transceiver with FCT speed characteristics is required. Compare against SOIC or SSOP variants if surface mount technology is preferred. Verify that the 12 mA/15 mA drive currents meet the load requirements of the connected circuitry.

Part Context

This part belongs to the CY74FCT245T family of standard transceivers. It serves as a parallel interface solution for connecting microprocessors to memory or peripheral devices. The PDIP-20 package distinguishes it from surface-mount equivalents like the CY74FCT245ATQCT or CY74FCT245TSOCT.

Replacement Considerations

Direct pin-compatible substitutes include other CY74FCT245 variants with different packages such as CY74FCT245ATQC (SSOP) or CY74FCT245TSOCT (SOIC). Verify package compatibility before substitution.
