Part Description: Octal D-type flip flop with clear


Part Details:

74VHCT273A OCTAL D-TYPE FLIP FLOP WITH CLEAR s HIGH SPEED: fMAX = 170 MHz (TYP.) at VCC = 5V s LOW POWER DISSIPATION:ICC = 4 µA (MAX.) at TA=25°C s COMPATIBLE WITH TTL OUTPUTS:VIH = 2V (MIN.), VIL = 0.8V (MAX) SOP TSSOP s POWER DOWN PROTECTION ON INPUTS & OUTPUTS s SYMMETRICAL OUTPUT IMPEDANCE: Table 1: Order Codes |IOH| = IOL = 8 mA (MIN) s BALANCED PROPAGATION DELAYS: PACKAGE T & R tPLH tPHL SOP 74VHCT273AMTR s OPERATING VOLTAGE RANGE: TSSOP 74VHCT273ATTR VCC(OPR) = 4.5V to 5.5V s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 273 edge of the clock pulse. When the CLEAR input is held low, the Q outputs s IMPROVED LATCH-UP IMMUNITY are held low independently of the other inputs. s LOW NOISE: VOLP = 0.9V (MAX.) Power down protection is provided on all inputsand outputs and 0 to 7V can be accepted on DESCRIPTION inputs with no regard to the supply voltage. This The 74VHCT273A is an advanced high-speed device can be used to interface 5V to 3V since all CMOS OCTAL D-TYPE FLIP FLOP WITH CLEAR inputs are equipped with TTL threshold. fabricated with sub-micron silicon gate and All inputs and outputs are equipped with double-layer metal wiring C2MOS technology. protection circuits against static discharge, giving Information signals applied to D inputs are them 2KV ESD immunity and transient excess transferred to the Q outputs on the positive going voltage.
