The CD74HCT646M96 is a 3-state buffer/line driver used in data and address buffering applications requiring high speed, small size, and low power consumption. It is pin-compatible with the standard 74HCT logic line receiver/buffer and is used to drive one or more data lines and/or address lines in a variety of microprocessor, logic, analog, and mixed-signal applications.

The CD74HCT646M96 is part of the HCT series of logic devices from Texas Instruments. HCT stands for high-speed CMOS technology and is used to indicate levels of performance and compatibility with TTL devices. The HCT technology offers significantly improved speed over the 74LS and 74/F family of TTL devices, yet can still be mixed and matched with either type in both logic gates and data buffers/line drivers.

The CD74HCT646M96 has an enable input (E) and active low outputs (Y0-Y15). The enable input controls the outputs, allowing the outputs to change state when the enable is LOW, and to stay in their off-state condition when the enable is HIGH. All of the outputs are active when the enable (E) input is low.

The device can be used in a variety of applications, including data and address buffering, data line expansion, and bus latching. The device can also be used in multiplexer and logic circuit applications where low logic levels are needed. It can also be used in control logic and arithmetic logic unit (ALU) implementations where the outputs can be used as address lines or as data outputs.

The CD74HCT646M96 works on a simple principle. When an enable signal is sent to the device (E), the state of all outputs is determined by the input. If the enable is LOW, then the outputs will follow the inputs. If the enable is HIGH, then the outputs will remain in their off-state condition. The device can operate from a single supply voltage (VDC) of 3V to 6V, and has a propagation delay of 3.00ns (MAX).

The CD74HCT646M96 is an ideal device for buffering and line driving applications requiring high speed, small size, and low power consumption. The device is pin compatible with the 74HCT family of logic devices, and can be used in a variety of microprocessor, logic, analog, and mixed-signal applications. The device features excellent speed performance with a maximum propagation delay of 3.00ns.
