MC74HC139ADR2G Description

Short technical summary and product information.

The MC74HC139ADR2G from ON Semiconductor is a high-performance silicon-gate CMOS Dual 1-of-4 Decoder/Demultiplexer. This device consists of two independent 1-of-4 decoders, each decoding a two-bit address to one of four active-low outputs. Active-low selects are provided for demultiplexing and cascading functions.

Key features include an operating voltage range of 2.0V to 6.0V and an output drive capability of 10 LSTTL loads. The outputs directly interface to CMOS, NMOS, and TTL logic families. It exhibits low input current and high noise immunity, characteristic of CMOS devices. The device is compliant with JEDEC Standard No. 7A.

Available in SOIC-16, TSSOP-16, and QFN16 packages, the MC74HC139ADR2G is suitable for surface mount applications. It is Pb-free, halogen-free/BFR-free, and RoHS compliant. The device is identical in pinout to the LS139 and its inputs are compatible with standard CMOS outputs, and with pull-up resistors, compatible with LSTTL outputs.
