The HEF40374BP,652 is an octal D-type flip-flop with 3-state buffered outputs, designed for use as an 8-bit positive edge-triggered storage register. It interfaces with a 3-state bus, transferring data on the D-inputs to storage during the LOW-to-HIGH transition of the clock input (CP).
The device features an active LOW output enable input (EO). A HIGH on EO forces the eight outputs to a high impedance OFF-state, while a LOW on EO allows the data in the register to appear at the outputs. The output stages offer high current capability, suitable for driving highly capacitive loads. The CP input includes hysteresis for improved noise rejection, and the E input has Schmitt-trigger action for tolerance to slower input rise and fall times.
This flip-flop operates with a supply voltage range of 3V to 15V and has a maximum clock frequency of 17 MHz. The maximum propagation delay is 80ns at 15V with a 50pF load. It is housed in a 20-DIP package and is suitable for through-hole mounting. The operating temperature range is -40°C to 85°C (TA).
The HEF40374B is pin and functionally compatible with the TTL ‘374’ device.
