CD4049UBM/CD4049UBC Hex Inverting Buffer

CD4050BM/CD4050BC Hex Non-Inverting Buffer

General Description

These 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 (V_DD). The input signal high level (V_IH) can exceed the V_DD 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 V_DD -- 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 V_DD

Applications

• CMOS hex inverter/buffer

• CMOS to DTL/TTL hex converter

• CMOS current ‘‘sink’’ or ‘‘source’’ driver

• CMOS high-to-low logic level converter
