74ACT174B 数据手册 ( 数据表 ) - STMicroelectronics

DESCRIPTION
The 74ACT174 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.
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 = 200MHz (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION:
   ICC = 4µA(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 = 24mA (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
