DESCRIPTION
The HEF4050B provides six non-inverting buffers with
high current output capability suitable for driving TTL or
high capacitive loads. 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.
