Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers.

It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This 8-bit D-type flipflop is controlled by a clock input (CP) and an Output Enable input (OE). When the OE input is HIGH, the eight outputs are in a high impedance state. ■ High speed: fMAX Protection circuits ensure that 0V to 7V can be applied to the input and output (Note 1) pins without regard to the supply voltage. This device can be used to interface 3V to 5V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. 140 MHz (typ) at TA 25qC ■ Power Down Protection is provided on all inputs and outputs. ■ Low Noise: VOLP 1.6V (max) ■ Low Power Dissipation: ICC 4 PA (max) @ TA 25qC ■ Pin and Function Compatible with 74HCT574 Note 1: Outputs in OFF-State.

With the Output Enable (OE) LOW, the contents of the eight flip-flops are available at the outputs. When the OE is HIGH, the outputs go to the high impedance state. Operation of the OE input does not affect the state of the flipflops. The VHCT574A consists of eight edge-triggered flip-flops with individual D-type inputs and 3-STATE true outputs. The buffered clock and buffered Output Enable are common to all flip-flops. The eight flip-flops will store the state of their individual D inputs that meet the setup and hold time requirements on the LOW-to-HIGH Clock (CP) transi- Logic Diagram Please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays. www.fairchildsemi.com 2 Recommended Operating Conditions (Note 6) 0.5V to 7.0V 0.5V to 7.0V Supply Voltage (VCC) DC Input Voltage (VIN) 4.5V to 5.5V Supply Voltage (VCC) DC Output Voltage (VOUT ) 0V to 5.5V Input Voltage (VIN) (Note 3) (Note 4) Input Diode Current (IIK) Output Diode Current (IOK) (Note 5) DC Output Current (IOUT ) DC VCC/GND Current (ICC) Storage Temperature (TSTG) 0.5V to VCC  0.5V 0.5V to 7.0V 20 mA r20 mA r25 mA r75 mA 65qC to 150qC Output Voltage (VOUT) 0V to VCC (Note 4) 0V to 5.5V 40qC to 85qC Operating Temperature (TOPR) Input Rise and Fall Time (tr, tf) VCC 5.0V r 0.5V 0 ns/V a 20 ns/V Note 2: Absolute Maximum Ratings are values beyond which the device may be damaged or have its useful life impaired.
