The DM74AS652NT is a 6-bit non-inverting buffer/line driver with active-low outputs and has been designed to support increase the speed of rapidly parallel operations and to interface data buses with differing voltage levels. This device is most commonly used in logic gates, memories, and data handling. It is also used in multiplexers, tristate, and bus switches.

This device is made up of two distinct logic components: a buffer/line driver and a line receiver. The buffer/line driver will take input signals from five separate sources, amplify them and drive the corresponding output to the appropriate voltage levels. The line receiver will take input signals from five separate sources, compare them and is able to, if necessary output an active-low state. This can be used to further control current flow.

The DM74AS652NT will have six inputs, each with a separate input buffer, these inputs are then connected to latch-enable (LE) and output enable (OE) pins. When LE is active the input buffer will latch data on the rising edge of the clock, allowing for synchronization of data. When OE is active a high impedance state is active, preventing current from the other external sources from being sent to the output.

The DM74AS652NT provides two output states, active-low, which is usually associated with a logic low voltage, and tristate, which is associated with a High-impedance state. When the output is active-low the device will actively drive the corresponding output line to the designated logic-low voltage level. When the output is in tristate, the device will not drive the corresponding output line and the line will remain in a high-impedance state. The DM74AS652NT will accept either a TTL or CMOS input level which provides wide compatibility.

The DM74AS652NT also boasts of a low power operation, meaning it requires relatively low power to operate. This low power is achieved with the use of a Schottky-clamped transistor in the input stages. This component invites the active-low signal to the output when the latch is enabled, the SchottkyClamped transistor amplifies the signal and plateaus the active-low signal output.

In addition to the features mentioned above, the DM74AS652NT is also fully characterized for supply voltage range, output short circuit protection, and logic high/low current levels up to specified ranges.

The DM74AS652NT is an ideal choice for low power, fast operation, and high levels of performance. Its compatibility with TTL and CMOS input levels make it flexible in a wide range of applications, from high speed buses and data handling, to memories and logic gates. The active-low output and tristate capabilities make it perfectly suitable for both line receivers and buffer/line drivers.
