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.

APPLICATION INFORMATION

Some examples of applications for the HEF4050B are:

  • HIGH sink current for driving 2 TTL loads

  • LOCMOS to DTL/TTL converter

  • HIGH-to-LOW level logic conversion
