Logic is one of the most important pillars of electronics. Logic devices include microprocessors, memory, field-programmable gate arrays, application-specific integrated circuits, analog circuits and so on. An important logical switch is the CD74HCT138M96, which can provide a most versatile solution for many applications requiring the multiplexing of data controlled by a variable number of variables.

The CD74HCT138M96 is a 3-to-8 line decoder/demultiplexer with inverting outputs. It uses Fairchild Semiconductor’s advanced CMOS technology and each output is asserted low in response to one of the combinations of active low address inputs. The common output enable "E" is used to either enable or disable all eight outputs at the same time. The output enable is active low and the decoder logic is active high.

The CD74HCT138M96 is typically used for driving Matrix Keypads, LCD displays and LED driver circuits. It can also be used for LED message boards where data is transferred from the display controller to the CD74HCT138M96 and the inverted signals are used to drive the LED displays. CD74HCT138M96 can be used as a simple three-to-eight demultiplexer in applications such as multiplexing a single bus to 8 external chips. Data can be routed to one of eight external registers or circuits using a three-bit address.

The CD74HCT138M96 works by decoding input signals into a range of binary numbers. A 4-bit binary number is typically utilized and is represented by an 8-bit Decoder where binary ‘0’s are represented by the value ‘1’ and binary ‘1’s are represented by the value ‘0’. Upon receiving the binary number from the input, the device looks into its internal register and finds the corresponding output. In this way, the inputs are converted into outputs, in accordance with the logic programmed into the device.

The CD74HCT138M96 operates from a single power supply. The static supply current of the part is typically 400 uA and when it is fully functional, the part draws around 10 mA for TTL output and approx 15 mA for CMOS output. The maximum switching frequency of the part is typically 400 kHz and it can operate from as low as a 3V supply.

The CD74HCT138M96 has a wide variety of uses, such as in applications utilizing matrix keypads, LCD displays and LED driver circuits. Additionally, the device can be used as a multiplexer, providing a flexible solution for a variety of signal applications such as data selection, analog and digital selection, address decoding, control signal generation and signal demultiplexing. It is also used in audio signal switching, serial-to-parallel conversion, multiplexers, signal routing, level translating and logic gates.

The CD74HCT138M96 is an ideal device for fast Data Decoding and Multiplexing as it can integrate numerous signals into one signal and vice versa. The device can be easily sourced from different distributor websites and is key in designing electronic systems with a high degree of accuracy and performance.
