The 74HCT251PW,112 is a high-speed CMOS logic signal switch, multiplexer and decoder. The device is designed using a production-grade CMOS technology for operation at 3.3V supply and is characterized for operation over a temperature range of -40°C to +85°C.

The device provides a wide range of design flexibility for applications that require switching control of digital signals and multiplexing of bidirectional data buses (e.g. data bus broadcasts from a microprocessor system). The 74HCT251PW,112 can be used to break up a single data bus into multiple, smaller, independent data buses which, when combined, create a single larger bus. It can also be used to generate complementary outputs which are the duals of the input data lines.

The 74HCT251PW,112 is a versatile device that can be used in a wide range of applications. It has multiple input and output features and is ideal for applications such as byte wide multiplexers/demultiplexers, address decode/decoders, logic switches, data multiplexing and demultiplexing, or bit level bus interface circuitry.

The 74HCT251PW,112 is composed of 8 identical circuits called logic gates. Each logic gate has two inputs (A and B), an output (Y) and an enable input (E). The output of a gate is high (1) when the inputs are both high (1). If either input is low (0) or the enable input is low (0), the output will be low (0). The enable input allows the outputs of the gates to be disabled (0) and so no signal will pass through the gates.

The 74HCT251PW,112 also features two additional enable inputs. Each of these enable inputs will enable or disable the entire device. This allows the device to be used as a global switch. By connecting these enable inputs to the processor’s control signal, the device will be turned on and off in unison.

The 74HCT251PW,112 is available in an 8-pin narrow SO or PDIP packages and operates in the temperature range of -40C to +85C. The device features low power consumption, a wide range of input and output features and is ideal for switching between multiple signals. It is suitable for applications such as address decoding, multiplexing, data routing and signal switching.

The 74HCT251PW,112 is an ideal switch for applications that require low power consumption and fast switching speed. It is also suitable for use in applications where logic signal switching, multiplexing, or address decode/decoding is required. It is available in an 8-pin narrow SO or PDIP packages and operates over a temperature range of -40°C to +85°C.
