NSC CD4512

CD4512BM/CD4512BC 8-Channel Buffered Data Selector
General Description
Features
The CD4512BM/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 TRISTATEÉ 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 TRI-STATE condition. Low
levels at both the Inhibit and (OE) inputs allow normal operation.

*AC Parameters are guaranteed by DC correlated testing.
Note 1: ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The tables of ‘‘Recommended Operating Conditions’’ and ‘‘Electrical Characteristics’’ provide conditions for actual device
operation.
Note 2: VSS e 0V unless otherwise specified.
Note 3: IOH and IOL are tested one output at a time.
Note 4: Capacitance guaranteed by periodic testing.
Note 5: CPD determines the no load AC power of any CMOS device. For complete explanation, see 54C/74C Family Characteristics Application Note, AN-90.
