MC54HCT574A

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Noninverting D Flip-Flop with LSTTL-Compatible Inputs High–Performance Silicon–Gate CMOS The MC54/74HCT574A is identical in pinout to the LS574. This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. Data meeting the setup time is clocked to the outputs with the rising edge of the Clock. The Output Enable input does not affect the states of the flip–flops, but when Output Enable is high, all device outputs are forced to the high–impedance state. Thus, data may be stored even when the outputs are not enabled. The HCT574A is identical in function to the HCT374A but has the flip–flop inputs on the opposite side of the package from the outputs to facilitate PC board layout. Output Drive Capability: 15 LSTTL Loads TTL NMOS Compatible Input Levels Outputs Directly Interface to CMOS, NMOS and TTL Operating Voltage Range: 4.5 to 5.5 V Low Input Current: 1.0 µ...
