MC14069UB Hex Inverter The MC14069UB hex inverter is constructed with MOS P–channel and N–channel enhancement mode devices in a single monolithic structure. These inverters find primary use where low power dissipation and/or high noise immunity is desired. Each of the six inverters is a single stage to minimize propagation delays. http://onsemi.com MARKING DIAGRAMS 14 PDIP–14 P SUFFIX CASE 646 MC14069UBCP AWLYYWW 1 14 SOIC–14 D SUFFIX CASE 751A 1 14 TSSOP–14 DT SUFFIX CASE 948G 1 500 – 55 to +125 – 65 to +150 260 mW °C °C °C SOEIAJ–14 F SUFFIX CASE 965 1 A = Assembly Location WL or L = Wafer Lot YY or Y = Year WW or W = Work Week 14 MC14069U AWLYWW 14 069U ALYW • Supply Voltage Range = 3.0 Vdc to 18 Vdc • Capable of Driving Two Low–Power TTL Loads or One Low–Pow [ ... ]
