HEF4049B Datasheet

Hex Inverting Buffers

Manufacturer: Philips Semiconductors (now NXP Semiconductors)

HEF4049B Overview

The HEF4049B provides six 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 mon bipolar logic elements is shown in the table below.
