ON MC14512 8-channel data selector Datasheet

MC14512B
8-Channel Data Selector
The MC14512B is an 8–channel data selector constructed with
MOS P–channel and N–channel enhancement mode devices in a
single monolithic structure. This data selector finds primary
application in signal multiplexing functions. It may also be used for
data routing, digital signal switching, signal gating, and number
sequence generation.

2. Maximum Ratings are those values beyond which damage to the device
may occur.
3. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high–impedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS
(Vin or Vout)
VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either VSS or VDD). Unused outputs must be left open.

3–STATE MODE OF OPERATION
Output terminals of several MC14512B 8–Bit Data
Selectors can be connected to a single date bus as shown.
One MC14512B is selected by the 3–state control, and the
remaining devices are disabled into a high–impedance “off”
state. The number of 8–bit data selectors, N, that may be
connected to a bus line is determined from the output drive
current, IOD, 3–state or disable output leakage current, ITL,
and the load current, IL, required to drive the bus line
(including fanout to other device inputs), and can be
calculated by:
N=
IOD – IL
+1
ITL
N must be calculated for both high and low logic state of the
bus line.
