Product Summary

The 74AC574 MOT is a high-speed, low power octal flip-flop with a buffered common Clock (CP) and a buffered common Output Enable (OE). The information presented to the D-type inputs is stored in the flip-flops on the LOW-to-HIGH Clock (CP) transition. The 74AC574 MOT is functionally identical to the AC/ACT374 except for the pinouts.

Parametrics

74AC574 absolute maximum ratings: (1)Supply Voltage (VCC): -0.5V to +7.0V; (2)DC Input Diode Current (IIK) VI = -0.5V: -20mA; (3)VI = VCC + 0.5V: +20mA; (4)DC Input Voltage (VI): -0.5V to VCC + 0.5V; (5)DC Output Diode Current (IOK) VO = -0.5V: -20mA; (6)VO = VCC + 0.5V: +20mA; (7)DC Output Voltage (VO): -0.5V to VCC + 0.5V; (8)DC Output Source or Sink Current (IO): ±50mA; (9)DC VCC or Ground Current per Output Pin (ICC or IGND): ±50mA; (10)Storage Temperature (TSTG): -65℃ to +150℃; (11)Junction Temperature (TJ) PDIP: 140℃.

Features

74AC574 features: (1)ICC and IOZ reduced by 50%; (2)Inputs and outputs on opposite sides of package allowing easy interface with microprocessors; (3)Useful as input or output port for microprocessors; (4)Functionally identical to AC/ACT374; (5)3-STATE outputs for bus-oriented applications; (6)Outputs source/sink 24 mA; (7)ACT574 has TTL-compatible inputs.
