DESCRIPTION
The AC174 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 .
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
■ HIGH SPEED:
fMAX =125 MHz (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION:
ICC = 8 µA (MAX.) at TA = 25 oC
■ HIGH NOISE IMMUNITY:
VNIH = VNIL = 28% VCC (MIN.)
■ 50Ω TRANSMISSION LINE DRIVING CAPABILITY
■ SYMMETRICAL OUTPUT IMPEDANCE:
|IOH| = IOL =24 mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ OPERATING VOLTAGE RANGE:
VCC (OPR) = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 174
■ IMPROVED LATCH-UP IMMUNITY
