Working Principle

The GD75232PWG4 is a bit-to-bit octal non-inverting driver designed to provide high speed data transfer. It consists of two equal sections, each consisting of four buffers. The four outputs of each section are connected to the inputs of the other, allowing double data rate.

The buffers can be connected in series to generate an output current of up to 500mA and swing signals up to 4V. The two supply voltages VCC1 and VCC2 can be either a positive or a negative voltage, and different voltage configurations can be applied, as described in the datasheet.

The outputs are protected against shorts to VCC1, VCC2, GND and each other. The buffers are configured to drive a standard load in a water-pooling or to drive a 50-Ohm transmission line. An on-chip Schottky diode bridge connects each output to VCC1 and VCC2, improving the ESD immunity of the device.

The inputs are compatible with LVTTL and LVCMOS, allowing for a wide variety of applications. The input levels are captured by edge-triggered D flip-flops with hysteresis for improved noise immunity. The outputs are disabled by the output enable (OE) signal, allowing for minimal power consumption when the device is not needed.

Conclusion

The GD75232PWG4 driver is a versatile and robust component suitable for a wide range of applications, especially in demanding and critical systems. Its high speed performance, reliable protection mechanisms and LVTTL/LVCMOS compatible inputs are some of the key features that make it an ideal choice for industrial, automotive and communication applications.
