CD4049

Hex Inverting Buffer

Other names for this product: 4049, CD 4049, CD4049UB,
Courtesy/Thanks to: Fairchild Semiconductor

Description: General Description

The CD4049UBC and CD4050BC hex buffers are monolithic
complementary MOS (CMOS) integrated circuits constructed
with N- and P-channel enhancement mode
transistors. These devices feature logic level conversion
using only one supply voltage (VDD). The input signal high
level (VIH) can exceed the VDD supply voltage when these
devices are used for logic level conversions. These
devices are intended for use as hex buffers, CMOS to DTL/
TTL converters, or as CMOS current drivers, and at VDD =
5.0V, they can drive directly two DTL/TTL loads over the
full operating temperature range.


Features

• Wide supply voltage range: 3.0V to 15V

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

range
• High source and sink current capability

• Special input protection permits input voltages greater
than VDD


Applications

• CMOS hex inverter/buffer

• CMOS to DTL/TTL hex converter

• CMOS current “sink” or “source” driver

• CMOS HIGH-to-LOW logic level converter
