HEF40373B
Datasheet
General description
The HEF40373B is an 8-bit transparent latch with 3-state buffered outputs. The output stages have high current output capability suitable for driving highly capacitive loads. The latch outputs follow the data inputs when the latch enable (E) is HIGH. When E is LOW, the data that meets the set-up times is latched. The 3-state outputs are controlled by the output enable input EO. A HIGH on EO causes the outputs to assume a high impedance OFF-state. The device features hysteresis on the E 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 HEF40373B is pin and functionally compatible with the TTL ?373? device.
Supply voltage range: 3 to 15 V.
