The 74HCT564N are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HCT564N are octal D-type flip-flops featuring separate D-type inputs for each flip-flop and inverting3-state outputs for bus oriented applications. A clock (CP) and an output enable (OE) input are common to all flip-flops. The 8 flip-flops will store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW-to-HIGH CP transition. When OE is LOW, the contents of the 8 flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops. The ?564? is functionally identical to the ?574? but has inverting outputs. The ?564? is functionally identical to the ?534?, but has a different pinning.Features:3-state inverting outputs for bus oriented applications8-bit positive-edge triggered registerCommon 3-state output enable inputIndependent register and 3-state buffer operationOutput capability: bus driverICC category: MSI20 pin DIP.
