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 outputs without damage or logic upset. In addition, all terminals are protected against ESD to at least 2000V.

ApplicationsGeneral Purpose CMOS Logic Buffer Driving All Four MOSFETs in an H-Bridge Direct Small Motor Driver Relay or Peripheral Drivers CCD Driver Pin-Switching Network Driver
The TC4467/TC4468/TC4469 devices are a family of four-output CMOS buffers/MOSFET drivers with 1.2 A peak drive capability. Unlike other MOSFET drivers, these devices have two inputs for each output. The inputs are configured as logic gates: NAND (TC4467), AND (TC4468) and AND/INV (TC4469).
The TC4467/TC4468/TC4469 drivers can continuously source 250 mA into ground referenced loads. These devices are ideal for direct driving low current motors or driving MOSFETs in a H-bridge configuration for higher current motor drive (see Section 5.0 for details). Having the logic gates onboard the driver can help to reduce component count in many designs.
The TC4467/TC4468/TC4469 devices are very robust and highly latch-up resistant. They can tolerate V of noise spiking on the ground line and can handle A of reverse current on the driver outputs.
The TC4467/4468/4469 devices are available in commercial, industrial and military temperature ranges.

Notice: Stresses above those listed under "Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

V ILOAD 100 µA (Note 1) V ILOAD 10 mA (Note 1) IOUT = 10 mA, VDD A mA Single OutputNote 1: Totem pole outputs should not be paralleled because the propagation delay differences from one to the other could cause one driver to drive high a few nanoseconds before another. The resulting current spike, although short, may decrease the life of the device. Switching times are ensured by design.
2: When driving all four outputs simultaneously in the same direction, VDD will be limited 16 V. This reduces the chance that internal dv/dt will cause high-power dissipation in the device.
3: The input threshold has approximately mV of hysteresis centered at approximately 1.5 V. Input rise times should be kept below 5 µsec to avoid high internal peak currents during input transitions. Static input levels should also be maintained above the maximum, or below the minimum, input levels specified in the "Electrical Characteristics" to avoid increased power dissipation in the device.
