Octal transparent latch with 3-state outputs

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.
