... OFF-state. The device also features hysteresis on all inputs to improve noise immunity. Schmitt-trigger action in the inputs makes the circuit highly tolerant to slower input rise and fall times. The HEF40245B is pin and functionally compatible with the TTL ‘245’ device. Fig.1 Pinning diagram. January 1995 ...
