Texas Instruments' CD74HCT138E is a reliable 3-to-8 line decoder/demultiplexer IC designed for address decoding and data routing applications. Its compatibility with standard TTL logic levels, low power consumption, and active low enable input make it a versatile component for digital systems. With low propagation delay for fast decoding and various package options for flexible circuit design, this IC is well-suited for memory address decoding, data routing, interface control, and signal demultiplexing tasks. Consider alternatives like the 74HC138 and CD4514 for similar functionalities in more complex systems
Data sheet acquired from Harris Semiconductor
DescriptionThe ’HC138, ’HC238, ’HCT138, and ’HCT238 are high speed silicon gate CMOS decoders well suited to memory address decoding or data routing applications. Both circuits feature low power consumption usually associated with CMOS circuitry, yet have speeds comparable to low power Schottky TTL logic. Both circuits have three binary select inputs (A0, A1 and A2). If the device is enabled, these inputs determine which one of the eight normally high outputs of the HC/HCT138 series will go low or which of the normally low outputs of the HC/HCT238 series will go high.
Two active low and one active high enables (E1\, E2\, and E3) are provided to ease the cascading of decoders. The decoder’s 8 outputs can drive 10 low power Schottky TTL equivalent loads.

it is CH340G chip but the PCBA is not suitable for programming arduino pro mini... but after little bit of reasearch i was able to hack it the way i want it to be :)
