GB4600

Description


The GB4600 is a high performance, monolithic unity gain video buffer made on Gennum's proprietary LSI process. The device features a stable wideband topology capable of driving high capacitance video busses.

Optimal system power/bandwidth can be achieved by using the high/low current mode select (I-SET). In addition, the GB4600 can be disabled by taking the ENABLE pin to ground. The ENABLE input is TTL and 5V CMOS compatible.

The GB4600 operates from ±4.5 to ±5.5V power supplies and typically draws 30mA of current when I-SET is not connected. The supply current drops by approximately 50% when I-SET is directly connected to VEE.

A typical application for the GB4600 is interfacing Gennum's wide range of video crosspoint switches. The 8 pin PDIP and 8 pin SOIC packaging is ideally suited for space restricted board layouts.
