HEF40374B - Octal D-type flip-flop with 3-state outputs

General Description

The HEF40374B is an octal D-type flip-flop with 3-state buffered outputs with a common clock input (CP).

The device is used primarily as an 8-bit positive edge-triggered storage register for interfacing with a 3-state bus.

Key Features

  • hysteresis on the CP input to improve noise rejection. Schmitt-trigger action in the E input makes the circuit highly tolerant to slower input rise and fall times. The HEF40374B is pin and functionally compatible with the TTL ‘374’ device. Supply voltage range: 3 to 15 V. Fig.1 Functional diagram. Fig.2 Pinning diagram.

The device is used primarily as an 8-bit positive edge-triggered storage register for interfacing with a 3-state bus. Data on the D-inputs is transferred to storage during the LOW-to-HIGH transition of the clock (CP) input.
