Product Overview: SN74LV138ATD - Texas Instruments

The SN74LV138ATD from Texas Instruments is a high-performance, low-voltage 3-to-8 line decoder/demultiplexer device designed to facilitate the implementation of general non-inverting decoder applications. This integrated circuit (IC) is particularly suitable for systems that require a reduction in power consumption without sacrificing speed and performance.

Key Features

• Logic Family: The SN74LV138ATD belongs to the LV family, which operates at a lower voltage range, typically 2V to 5.5V, providing a balance between speed and power efficiency.
• Decoding Capability: It can decode a 3-bit binary input into one of eight mutually exclusive outputs, making it ideal for a wide range of applications such as memory chip select decoding and data routing.
• Output Drive Capability: This device can drive up to 4 mA at the output, allowing for direct drive of small LEDs or interfacing with other logic families.
• Schmitt-Trigger Inputs: The inputs feature Schmitt-trigger action, which allows the IC to handle slower input rise and fall times, providing noise immunity and ensuring stable output transitions.

Product Specifications

• Package: The SN74LV138ATD is offered in a TSSOP (Thin Shrink Small Outline Package) with 16 pins, providing a compact footprint for space-constrained applications.
• Operating Temperature: It is designed to operate over a broad temperature range from -40°C to 85°C, making it suitable for industrial environments.
• Propagation Delay: The device boasts a typical propagation delay of 4.5 ns at 5V, ensuring fast response times for critical applications.

Applications

The SN74LV138ATD is versatile and can be used in various applications, including:

• Memory chip select decoding
• Data multiplexing
• Address decoding for microprocessors
• Control signal gating
• Function generator

With its robust design and reliable performance, the SN74LV138ATD from Texas Instruments is an excellent choice for designers who require a low-power, high-speed decoder/demultiplexer for their digital applications.
