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

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. Data on the D-inputs is transferred to storage during the LOW-to-HIGH transit.

HEF40374B 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.
