DESCRIPTION
The ACT174 is an high-speed CMOS HEX D-TYPE FLIP FLOP WITH CLEAR fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power applications mantaining high speed operation similar to eqivalent Bipolar Schottky TTL.
Information signals applied to D inputs are transfered to the Q output on the positive going edge of the clock pulse.
When the CLEAR input is held low, the Q outputs are held low independentelyof the other inputs .
The device is designed to interface directly High Speed CMOS systems with TTL, NMOS and CMOS output voltage levels.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
■ HIGH SPEED:
fMAX = 200 MHz (TYP.) at VCC =5V
■ LOW POWER DISSIPATION:
ICC = 8 µA (MAX.) at TA = 25 °C
■ COMPATIBLE WITH TTL OUTPUTS
VIH = 2V (MIN), VIL = 0.8V (MAX)
■ 50Ω TRANSMISSION LINE DRIVING CAPABILITY
■ SYMMETRICAL OUTPUT IMPEDANCE:
|IOH| = IOL =24 mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ OPERATING VOLTAGE RANGE:
VCC (OPR) = 4.5V to 5.5V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 174
■ IMPROVED LATCH-UP IMMUNITY
