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.

LOGIC-INPUT CMOS QUAD DRIVERS TC4467 TC4468 TC4469 Supply Bypassing Three components make up total package power dissipation: Large currents are required to charge and discharge large capacitive loads quickly. For example, charging a 1000 pF load to 18V in 25 ns requires 0.72A from the device's power supply. To guarantee low supply impedance over a wide frequency range, a 1 µF film capacitor in parallel with one or two low-inductance 0.1 µF ceramic disk capacitors with short lead lengths (<0.5 in.

LOGIC-INPUT CMOS QUAD DRIVERS TC4467 TC4468 TC4469 Transition power dissipation arises in the complementary configuration (TC446X) because the output stage N-channel and P-channel MOS transistors are ON simultaneously for a very short period when the output changes. The transition power dissipation is approximately: Maximum operating temperature: TJ – θJA (PD) = 141°C, where: TJ = Maximum allowable junction temperature (+150°C) θJA = Junction-to-ambient thermal resistance (83.3°C/W) 14-pin plastic package.
