HD74ALVCH16820
3.3-V 10-bit Flip Flops with Dual Outputs
ADE-205-170B 3rd. Edition December 1999 Description
flip flops HD74ALVCH16820 edge triggered D-type flip flops. positive transition clock (CLK) input, device provides true data outputs. buffered output enable (OE) input used place outputs either normal logic state (high logic level) high impedance state. high impedance state, outputs neither load drive lines significantly. high impedance state increased drive provide capability drive lines without need interface pullup components. input does affect internal operation flip flops. data retained data entered while outputs high impedance state. Active hold circuitry provided hold unused floating data inputs valid logic level.
Features
Typical ground bounce (@VCC 25°C) Typical undershoot (@VCC 25°C) High output current hold data inputs eliminates need external pullup pulldown resistors
