Product Information

CD4049UBC • CD4050BC Hex Inverting Buffer • Hex Non-Inverting Buffer October 1987 Revised January 1999 CD4049UBC • CD4050BC Hex Inverting Buffer • Hex Non-Inverting Buffer General Description The CD4049UBC and CD4050BC 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 (VDD ). The input signal high level (VIH) can exceed the VDD 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 VDD = 5.0V, they can drive directly two DTL/TTL loads over the full operating temperature range. Features s Wide supply voltage range: 3.0V to 15V s Direct drive to 2 TTL loads at 5.0V over full temperature range s High source and sink current capability s Special input protection permits input voltages greater than VDD Applications • CMOS hex inverter/buffer • CMOS to DTL/TTL hex converter • CMOS current “sink” or “source” driver • CMOS HIGH-to-LOW logic level converter Ordering Code: Order Number CD4049UBCM CD4049UBCN CD4050BCM CD4050BCN Package Number M16A N16E M16A N16E Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150” Narrow 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150” Narrow 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide Devices also available in Tape and Reel.
