IW4049B
Description
The IW4049B is hex buffers and feature logic-level conversion using only one supply (voltage Vcc).The
input- signal high (Vih) can exceed the Vcc supply voltage when these devices are used for logic -level
conversions. These devices are intended for use as CMOS to DTL/TTL converters
