The MC74HC138ADTR2G is a three-to-eight line decoder multiplexer logic device. It is classified under the Logic - Signal Switches, Multiplexers, Decoders category and offers superior performance in applications ranging from digital fan control to computer interface and communications. The MC74HC138ADTR2G offers low power consumption and a wide operating temperature range.

The MC74HC138ADTR2G has three active-low data input lines (A, B and C), one active-high enable input (G1) and eight active-high output lines (Y0 to Y7). The device is designed to respond to binary coded signals on the A, B and C inputs. The enable input (G1) is used to enable or disable the operation of the device.

When the enable input (G1) is in the low logic state, the device is disabled and the output logic levels will assume the high state. When the enable input (G1) is in the high logic state, the device will assume the binary coded data applied to the A, B and C inputs and the corresponding outputs of the MC74HC138ADTR2G will assume the low level.

The device has an operating range of -55° C to 125° C that makes it an ideal choice for digital fan control applications. In fan control applications, the MC74HC138ADTR2G is used to sense the input of a temperature sensor or switch and control the output of a fan motor. The device can be used in other applications as well, such as computer interface and communications.

The MC74HC138ADTR2GDevice is a CMOS integrated circuit and is fabricated with silicon gate CMOS technology and is processed in compliance with JESD709-A. This device features low input current and a high noise immunity of 200 mV, making it highly reliable and suitable for a wide range of logic-level and digital switching applications.

In summary, the MC74HC138ADTR2G is a three-to-eight line decoder multiplexer logic device that offers superior performance in applications ranging from digital fan control to computer interface and communications. It is classified under the Logic - Signal Switches, Multiplexers, Decoders category and offers low power consumption and a wide operating temperature range of -55° C to 125° C. The device is a CMOS integrated circuit that features low input current and a high noise immunity of 200 mV, making it ideal for logic-level and digital switching applications.
