SN74AHCT138MPWREP - Texas Instruments

The SN74AHCT138MPWREP is a high-performance, military-grade integrated circuit designed and manufactured by Texas Instruments (TI), a leader in semiconductor solutions. This device belongs to the 'AHCT' family and is specifically engineered to meet the stringent requirements of space-constrained and harsh environment applications, offering enhanced product performance and reliability.

The SN74AHCT138MPWREP is a 3-to-8 line decoder/demultiplexer, which features three binary select inputs (A, B, and C), an active-low enable input (G1), and two active-high enable inputs (G2A and G2B). When the device is enabled, the binary input code applied to the A, B, and C inputs results in the demultiplexing of data to one of the eight output lines. Outputs are high-impedance when disabled, allowing for easy multiplexing and data routing.

This device is characterized for operation from -55°C to 125°C, making it an excellent choice for military and aerospace applications where temperature extremes are common. The SN74AHCT138MPWREP comes in a TSSOP (Thin Shrink Small Outline Package) with 16 pins, providing a compact footprint for space-limited printed circuit boards (PCBs).

Key features of the SN74AHCT138MPWREP include:

• Enhanced High-Speed CMOS logic.
• Typical operating voltage range of 4.5V to 5.5V.
• Low power consumption, with a typical ICC of only 4µA max.
• High noise immunity characteristic of CMOS devices.
• Output drive capability of up to 15 LSTTL loads.
• High-impedance outputs to support line sharing.
• Support for military temperature range (-55°C to 125°C).

Applications for the SN74AHCT138MPWREP are diverse and include satellite systems, military hardware, avionics, missile guidance systems, and space vehicles. Its robust design ensures reliable operation in extreme conditions, making it an indispensable component for critical missions and high-reliability systems.

With Texas Instruments' commitment to quality and long-term reliability, the SN74AHCT138MPWREP is a logical choice for designers seeking a dependable decoding/demultiplexing solution for their high-endurance projects.
