74HCT245N,652

Overview

The 74HCT245N,652 is an octal bus transceiver featuring non-inverting 3-state outputs in both send and receive directions. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device includes an output enable input (OE) for bus isolation and a direction control input (DIR). Propagation delay is typically 10 ns at 5 V with a 15 pF load.

Feature Summary

• Octal bidirectional bus interface
• Non-inverting 3-state outputs
• ESD protection exceeding 2000 V HBM

Applications

• Bus-oriented transfers
• Clock drivers
• Bidirectional data bus interfaces

Procurement Notes

Verify the component matches the specified NXP part number 74HCT245N,652. Confirm the package type is DIP-20 (SOT146-1) and that it meets the required temperature range of -40 °C to +125 °C. Ensure the datasheet revision aligns with current manufacturing standards before procurement.

Selection Notes

Select this component when interfacing between TTL-compatible logic families and CMOS buses. It is suitable for applications requiring high-speed data transfer with direction control. Verify that the system voltage remains within the 4.5 V to 5.5 V operating range to ensure proper functionality.

Part Context

This device belongs to the 74HCT series, which provides pin compatibility with Low-Power Schottky TTL (LSTTL). It is manufactured by NXP Semiconductors and is designed for high-speed Si-gate CMOS technology. The 'N' suffix indicates the DIP-20 plastic dual in-line package configuration.

Replacement Considerations

The 74HC245N,652 serves as a functional alternative but requires a 2.0 V to 6.0 V supply range instead of the HCT-specific 4.5 V to 5.5 V range. Ensure voltage levels are compatible before substitution.
