High–Performance Silicon–Gate CMOS
The MC74HC4351A utilizes silicon–gate CMOS technology to achieve
fast propagation delays, low ON resistances, and low OFF leakage currents.
These analog multiplexers/demultiplexers control analog voltages that may
vary across the complete power supply range (from VCC to VEE).
The Channel–Select inputs determine which one of the Analog Inputs/
Outputs is to be connected, by means of an analog switch, to the Common
Output/Input. The data at the Channel–Select inputs may be latched by
using the active–low Latch Enable pin. When Latch Enable is high, the latch
is transparent. When either Enable 1 (active low) or Enable 2 (active high) is
inactive, all analog switches are turned off.
The Channel–Select and Enable inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with LSTTL
outputs.
The device has been designed so the ON resistance (Ron) is more linear
over input voltage than Ron of metal–gate CMOS analog switches.
For multiplexers/demultiplexers without latches, see the HC4051A,
HC4052A, and HC4053A.
