Overview

The MC14049B Hex Inverter/Buffer and MC14050B Noninverting Hex Buffer are constructed with MOS P-Channel and N-Channel enhancement mode devices in a single monolithic structure. These complementary MOS devices find primary use where low power dissipation and/or high noise immunity is desired. These devices provide 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 devices are used as a CMOS-to-TTL/DTL converter (VDD = 5.0 V, VOL <= 0.4 V, IOL >= 3.2 mA).

Note that pins 13 and 16 are not connected internally on these devices; consequently connections to these terminals will not affect circuit operation.

  • High Source and Sink Currents
  • High-to-Low Level Converter
  • Supply Voltage Range = 3.0 V to 18 V
  • VIN can exceed VDD
  • Meets JEDEC B Specifications
  • Improved ESD Protection On All Inputs
  • Pb-Free Packages are Available*

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
