MC14049UB Datasheet

Buffers & Line Drivers


The MC14049UB hex inverter/buffer is constructed with MOS P−channel and N−channel enhancement mode devices in a single monolithic structure. This complementary MOS device finds primary use where low power dissipation and/or high noise immunity is desired.This device provides logic−level conversion using only one supply voltage, VDD. The input−signal high level (VIH) can exceed the VDD supply voltage for logic−level conversions. Two TTL/DTL Loads can be driven when the device is used as CMOS−to−TTL/DTL converters (VDD = 5.0 V, VOL  0.4 V, IOL ≥ 3.2 mA). Note that pins 13 and 16 are not connected internally on this device; consequently connections to these terminals will not affect circuit operation. MC14049UB Features • High Source and Sink Currents• High−to−Low Level Converter• Supply Voltage Range = 3.0 V to 18 V• Meets JEDEC UB Specifications• VIN can exceed VDD• Improved ESD Protection on All Inputs• These Devices are Pb−Free and are RoHS Compliant
