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 HEF40373B MSI 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. Fig.1 Functional diagram. Fig.2 Pinning diagram.
