GENERAL DESCRIPTION
The TC446X family of four-output CMOS buffer/drivers
are an expansion from our earlier single- and dual-output
drivers. Each driver has been equipped with a two-input
logic gate for added flexibility.
The TC446X drivers can source up to 250 mA into loads
referenced to ground. Heavily loaded clock lines, coaxial
cables, and piezoelectric transducers can all be easily
driven with the 446X series drivers. The only limitation on
loading is that total power dissipation in the IC must be kept
within the power dissipation limits of the package.
The TC446X series will not latch under any conditions
within their power and voltage ratings. They are not subject
to damage when up to 5V of noise spiking (either polarity)
occurs on the ground line. They can accept up to half an amp
of inductive kickback current (either polarity) into their out-
puts without damage or logic upset. In addition, all terminals
are protected against ESD to at least 2000V.
