Description

The 74LVC138APW is a high-performance CMOS device from the 74LVC family, designed for low voltage applications. It functions as a 3-to-8 line decoder/demultiplexer, which means it takes a 3-bit binary input and decodes it to one of eight outputs. The device is commonly used in applications requiring data routing, such as memory address decoding or data demultiplexing.
Key features of the 74LVC138APW include its ability to operate over a wide voltage range from 1.2V to 5.5V, making it suitable for both 3.3V and 5V systems. It offers high-speed operation with low power consumption, which is advantageous in battery-powered devices. The device also includes active-low enable inputs, allowing for multiple devices to be used in larger decoding schemes.
Packaged in a TSSOP (Thin Shrink Small Outline Package), the 74LVC138APW is suitable for space-constrained applications. Its combination of speed, low power, and versatility makes it a popular choice in digital logic design.

Pinout

The 74LVC138APW is a 16-pin small-outline package (SOP) integrated circuit. It is a high-speed 3-to-8 line decoder/demultiplexer. This IC accepts three binary weighted address inputs (A0, A1, A2) and, based on these inputs, decodes them to activate one of the eight outputs (Y0 to Y7), with the remaining outputs being deactivated.
The device functions with three enable inputs (E1, E2, E3). E1 and E2 are active-low, meaning the IC is enabled when these inputs are low. E3 is active-high, meaning it is enabled when this input is high. The combination of these enable pins allows for cascading of multiple devices for decoding larger numbers of input signals. When the device is enabled, one of the eight outputs will be low, while the others remain high, corresponding to the binary value of the inputs A0 to A2. This makes the 74LVC138APW suitable for applications requiring decoding, demultiplexing, or memory address decoding.
