SN74AHCT139QPWRQ1

Signal Switches, Multiplexers, Decoders Overview

The SN74AHCT139QPWRQ1 is an automotive-grade dual 2-line to 4-line decoder or demultiplexer from Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features TTL-compatible inputs with balanced CMOS push-pull outputs. The device meets AEC-Q100 standards for Grade 1, supporting temperatures from -40°C to +125°C. Propagation delay is typically 7.2ns at 5V with 15pF load, and maximum latch-up performance exceeds 250mA per JESD 17.

Signal Switches, Multiplexers, Decoders Feature Summary

AEC-Q100 qualified for automotive applications with specified temperature grades and ESD classifications.
TTL-compatible CMOS inputs designed for interfacing with standard logic devices.
Balanced CMOS push-pull outputs capable of sinking and sourcing similar currents.

Signal Switches, Multiplexers, Decoders Applications

High-performance memory decoding systems
Data routing applications requiring short propagation delays
Driving indicator LEDs

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific package type (TSSOP-16) against design requirements. Confirm that the operating environment remains within the specified -40°C to +125°C range. Ensure input signals transition quickly to prevent oscillations due to the TTL-compatible nature of the inputs. Check that output loads do not exceed the absolute maximum ratings to avoid damage.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when low propagation delay is critical for system timing in automotive environments. The TTL-compatible input threshold simplifies interface design with legacy logic families. Verify that the 4.5V to 5.5V supply voltage aligns with the system power architecture. Consider the TSSOP-16 package dimensions for PCB layout constraints.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74AHCT139-Q1 family of automotive decoders. It provides two independent 2-to-4 line decoding channels within a single integrated circuit. The device is optimized for minimizing system decoding effects in high-speed memory architectures where decoder delay must be negligible relative to memory access times.
