No Preview Available ! TECHNICAL DATA Quad 3-State Noninverting Buffers High-Performance Silicon-Gate CMOS IN74HC125A The IN74HC125A is identical in pinout to the LS/ALS125. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The IN74HC125A noninverting buffers are designed to be used with 3- state memory address drivers, clock drivers, and other bus-oriented systems. The devices have four separate output enables that are active-low. • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V • Low Input Current: 1.0 µA • High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION IN74HC125AN Plastic IN74HC125AD SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 14 =VCC PIN 7 = GND 118 FUNCTION TABLE Inputs A OE HL LL XH Output Y H L Z X = don’t care Z = high impedance 1 page IN74HC125A Figure 3.
