DESCRIPTION
The 74AC174 is an advanced high-speed CMOS HEX D-TYPE FLIP FLOP WITH CLEAR fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology.
Information signals applied to D inputs are transferred 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 independentely of 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 = 250MHz (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION:
ICC = 4µA(MAX.) at TA=25°C
■ HIGH NOISE IMMUNITY:
VNIH = VNIL = 28 % VCC (MIN.)
■ 50Ω TRANSMISSION LINE DRIVING CAPABILITY
■ SYMMETRICAL OUTPUT IMPEDANCE:
|IOH| = IOL = 24mA (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
