| CD4512BC 8-Channel Buffered Data Selector October 1987 Revised April 2002 CD4512BC 8-Channel Buffered Data Selector General Description The CD4512BC buffered 8-channel data selector is a complementary MOS (CMOS) circuit constructed with N- and P-channel enhancement mode transistors. This data selector is primarily used as a digital signal multiplexer selecting 1 of 8 inputs and routing the signal to a 3-STATE output. A high level at the Inhibit input forces a low level at the output. A high level at the Output Enable (OE) input forces the output into the 3-STATE condition. Low levels at both the Inhibit and (OE) inputs allow normal operation. Features s Wide supply voltage range: s 3-STATE output s Low quiescent power dissipation: 0.25 W/package (typ.) @ VCC = 5.0V s Plug-in replacement for Motorola MC14512 3.0V to 15V s High noise immunity: 0.45 VDD (typ.) Ordering Code: Order Number CD4512BCM CD4512BCN Package Number 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 Devices also available in Tape and Reel. Specify by appending suffix "X" to the ordering code.

They are not meant to imply that the devices should be operated at these limits. The Recommended Operating Conditions and Electrical Characteristics table provide conditions for actual device operation. Note 2: VSS = 0V unless otherwise specified.
