- Relay Driver Package Type General Description The TC1412/TC1412N are 2A CMOS buffers/drivers. They will not latch-up under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking of either polarity occurs on the ground pin. They can accept, without damage or logic upset, up to 500 mA of current of either polarity being forced back into their output. All terminals are fully protected against up to 4 kV of electrostatic discharge. As MOSFET drivers, the TC1412/TC1412N can easily charge a 1000 pF gate capacitance in 18 nsec with matched rise and fall times, and provide low enough impedance in both the ON and the OFF states to ensure the MOSFET’s intended state will not be affected, even by large transients. The leading and trailing edge propagation delay times are also matched to allow driving short-duration inputs with greater accuracy. 2 6,7 Inverting 8-Pin MSOP/PDIP/SOIC VDD OUT GND VDD IN NC GND OUT TC1412 NC = No Internal Connection 2 6,7 Non-Inverting TC1412N VDD IN NC GND VDD OUT GND OUT NOTE: Duplicate pins must be connected together for proper operation. 2A High-Speed MOSFET Drivers

3.0 PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 3-1. TABLE 3-1: PIN FUNCTION TABLE
3.1 Supply Input (V DD)
The VDD input is the bias supply for the MOSFET driver and is rated for 4.5V to 16V with respect to the ground pin. The V DD input should be bypassed to ground with a local ceramic capacitor. The value of the capacitor should be chosen based on the capacitive load that is being driven. A value of 1.0 µF is suggested.
3.2 Control Input (INPUT)
The MOSFET driver input is a high-impedance, TTL/CMOS-compatible input. The input has 300 mV of hysteresis between the high and low thresholds which prevents output glitching even when the rise and fall time of the input signal is very slow.
3.3 CMOS Push-Pull Output
(OUTPUT) The MOSFET driver output is a low-impedance, CMOS push-pull style output, capable of driving a capacitive load with 2A peak currents.
3.4 Ground (GND)
The ground pins are the return path for the bias current and for the high peak currents that discharge the load capacitor. The ground pins should be tied into a ground plane or have very short traces to the bias supply source return.
