CD4049UBC • CD4050BC

Hex Inverting Buffer •

Hex Non-Inverting Buffer

General Description

The CD4049UBC and CD4050BC hex buffers are mono-

lithic complementary MOS (CMOS) integrated circuits con-

structed with N- and P-channel enhancement mode

transistors. These devices feature logic level conversion

devices are used for logic level conversions. These

devices are intended for use as hex buffers, CMOS to DTL/

5.0V, they can drive directly two DTL/TTL loads over the

full operating temperature range.

Features

s Wide supply voltage range:

3.0V to 15V

s Direct drive to 2 TTL loads at 5.0V over full temperature

range

s High source and sink current capability

s Special input protection permits input voltages greater

Applications

• CMOS hex inverter/buffer

• CMOS to DTL/TTL hex converter

• CMOS current “sink” or “source” driver

• CMOS HIGH-to-LOW logic level converter

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
