IN74AC299 Datasheet | IK Semiconductor

features a multiplexed parallel input/output data port to achieve full 8-bit handling in a 20 pin package. Due to the large output drive capability and the 3-state feature , this device is ideally suited for interface with bus lines in a bus-oriented system. Two Mode-Select inputs and two Output Enable inputs are used to choose the mode of operation as listed in the Function Table. Synchronous parallel loading is acplished by taking both Mode Select lines, S1 and S2, high. This places the outputs in the highimpedance state, which permits data applied to the data port to be clocked into the register. Reading out of the register can be acplished when the outputs are enabled. The active-low asynchronous Reset overrides all other inputs. - Outputs Directly Interface to CMOS, NMOS, and TTL - Operating Voltage Range: 2.0 to 6.0 V - Low Input Current: 1.0 µA; 0.1 µA @ 25°C - High Noise Immunity Characteristic of CMOS Devices - Outputs Source/Sink 24 m A ORDERING INFORMATION IN74AC299N Plastic IN74AC299DW SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT w w w .d e e h s a t a . u t4 m o c PIN 20=VCC PIN 10 = GND ..
