DM74ALS5245N

Overview

The DM74ALS5245N is an octal bus transceiver designed for asynchronous two-way communication between data buses. It operates within a supply voltage range of 4.5V to 5.5V and supports a free-air operating temperature from 0°C to +70°C. The device features TTL-compatible input levels (VIH min 2V, VIL max 0.8V) and provides high-level output current of -15mA and low-level output current of 24mA. Propagation delay ranges from 3ns to 10ns, with output enable/disable times up to 20ns.

Feature Summary

Input hysteresis improves noise rejection
Low output noise generation
High input noise immunity
PNP inputs reduce input loading

Applications

Asynchronous two-way communication between data buses
Bus isolation via high impedance mode
Direction control for A-to-B or B-to-A transmission

Procurement Notes

Verify the component status as discontinued by onsemi/Fairchild. Confirm package type N20A (PDIP-20). Check RoHS compliance documentation. Ensure replacement parts match electrical characteristics if sourcing alternatives.

Selection Notes

Select this component for applications requiring octal bidirectional data transfer with TTL logic compatibility. Consider the specific propagation delays and drive currents for signal integrity. Verify thermal requirements against the specified operating temperature range.

Part Context

This part belongs to the 74ALS series of logic devices, utilizing advanced oxide-isolated, ion-implanted Schottky TTL process technology. It is manufactured by onsemi (formerly Fairchild Semiconductor). The PDIP-20 package is standard for through-hole mounting.
