Since input voltages in excess of the buffers’ supply voltage are permitted, the buffers may also be used to convert logic levels of up to 15 V to standard TTL levels. Their guaranteed fan-out into common bipolar logic elements is shown in the table below. Product specification HEF4050B buffers Fig.2 Pinning diagram. Fig.1 Functional diagram.
