SN74AHCT138DBRG4

Signal Switches, Multiplexers, Decoders Overview

The SN74AHCT138DBRG4 is a 3-line to 8-line decoder/demultiplexer from Texas Instruments, housed in a 16-pin SSOP package. It operates within a supply voltage range of 1.5 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. The device features TTL-voltage compatible inputs with high-level input voltage (VIH) at 2 V and low-level input voltage (VIL) at 0.8 V. Output drive capabilities include ±8 mA for both high and low states. Propagation delays are specified up to 13 ns under a 50 pF load condition.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'G4' against current manufacturer documentation to confirm compliance status and material specifications. Ensure the SSOP package variant matches the required board layout dimensions. Confirm that the -40°C to +85°C industrial temperature rating aligns with the target application environment requirements before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when TTL-compatible logic levels are required for CMOS-based designs. The AHCT series ensures compatibility with standard TTL outputs while maintaining CMOS noise immunity. Verify that the 16-pin SSOP footprint fits the available PCB space and that the thermal resistance characteristics are adequate for the expected power dissipation in the specific system configuration.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SNx4AHCT138 family of 3-line to 8-line decoders and demultiplexers manufactured by Texas Instruments. The family includes various package options such as SOIC, PDIP, and VQFN. The SN74 variant denotes commercial grade operation, distinguishing it from the SN54 military-grade counterpart which supports a wider temperature range.
