PIN DESCRIPTIONS

The descriptions of the pins are listed in Table 3-1.

TABLE 3-1:

PIN FUNCTION TABLE

3.1

Supply Input (VDD)

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 VDD 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 3A 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.

3.5

No Connect (NC)

No internal connection.

No.
