SN74LV138ATDGVR - Texas Instruments 3-to-8 Line Decoder/Demultiplexer
The SN74LV138ATDGVR by Texas Instruments is a high-performance, 3-to-8 line decoder/demultiplexer designed to facilitate the hardware management of digital signal lines. With its advanced low-voltage CMOS technology, it offers optimal power consumption and speed for a wide array of electronic applications, from consumer electronics to sophisticated industrial systems.
This integrated circuit (IC) is capable of decoding three binary input signals into one of eight mutually exclusive outputs. The device features three address inputs (A, B, and C), an active-low enable input (G1), and two active-high enable inputs (G2A and G2B). When the enable conditions are met, the binary coded input data is decoded and an active-low output (Y0 - Y7) is produced.
The SN74LV138ATDGVR operates over a broad voltage range from 2V to 5.5V, making it versatile for interfacing with both TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide Semiconductor) logic levels. This flexibility ensures that the device can be easily integrated into a variety of system designs without the need for additional level-shifting hardware.
Key features of the SN74LV138ATDGVR include:
- Support for mixed-mode voltage operation
- Significant power reduction compared to LSTTL logic ICs
- Output drive capability of up to 8 mA at 5V
- Multiple package options, with the DGVR variant housed in a compact TVSOP package
- High impedance state during power down
- Latch-up performance exceeding 250 mA per JESD 17
With its small footprint and low-power operation, the SN74LV138ATDGVR is an excellent choice for space-constrained applications. It is commonly used in multiplexing signals, address decoding for memory devices, and in the selection and control of multiple peripheral devices. The device's high level of integration and ease of use make it a go-to solution for designers looking to streamline their digital logic operations.
