SN74ABT827PW: 10-Bit Bus Interface D-Type Latch by Texas Instruments

The SN74ABT827PW from Texas Instruments is a high-performance, 10-bit bus interface D-type latch designed for 4.5-V to 5.5-V VCC operation. This integrated circuit is a member of the ABT family, which is known for its high drive and fast switching characteristics, making it an excellent choice for interfacing with bus lines in a wide range of applications.

The device features 10 D-type latches with 3-state bus driving outputs. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs. A buffered output-enable (OE) input can be used to place the ten outputs in either a normal logic state (high or low logic levels) or the high-impedance state. In the latter case, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without need for interface or pullup components.

OE does not affect the internal operations of the latch. Old data can be retained or new data can be entered while the outputs are off. The SN74ABT827PW is characterized for operation from -40°C to 85°C, making it suitable for industrial applications.

The device comes in a 24-pin TSSOP (Thin Shrink Small Outline Package) which is ideal for space-constrained applications. The SN74ABT827PW offers a clear functional edge with its fast propagation delays and low-glitch outputs, ensuring reliable and efficient operation in high-speed data capture scenarios.
