Octal D-type flip-flop with 3-state outputs
HEF40374B
MSI
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. Data on
the D-inputs is transferred to storage during the
LOW-to-HIGH transition of the clock (CP) input. The
3-state output buffers are controlled by an active LOW
output enable input (EO). A HIGH on EO forces the eight
outputs to a high impedance OFF-state. When EO is
LOW, the data in the register appears at the outputs.
The output stages have high current output capability
suitable for driving highly capacitive loads.
The device 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.
