HD74ALVCH162820 - 3.3-V 10-bit Flip Flops with Dual Outputs and 3-state Outputs

General Description

The HD74ALVCH162820 flip flops are edge triggered D-type flip flops.

On the positive transition of the clock (CLK) input, the device provides true data at the Q outputs.

Key Features

  • VCC = 2.3 V to 3.6 V.
  • Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C).
  • Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C).
  • High output current ±12 mA (@V CC = 3.0 V).
  • Bus hold on data inputs eliminates the need for external pullup / pulldown resistors.
  • All outputs have equivalent 26 Ω series resistors, so no external resistors are required. HD74ALVCH162820 Function Table Inputs OEn L L L H.

HD74ALVCH162820 3.3-V 10-bit Flip Flops with Dual Outputs and 3-state Outputs ADE-205-185B (Z) 3rd. Edition December 1999 Description The HD74ALVCH162820 flip flops are edge triggered D-type flip flops. On the positive transition of the clock (CLK) input, the device provides true data at the Q outputs. A buffered output enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a high impedance state. In the high impedance state, the outputs neither load nor drive the bus lines significantly. The high impedance state and increased drive provide the capability to drive bus line without need for interface or pullup components. OE does not affect the internal operations of the flip flops.
