... Data Sheet 330MHz, Low Power, Current Feedback Video Operational Amplifier with Output Disable The HFA1145 is a high speed, low power current feedback amplifier built with Intersil’s proprietary complementary bipolar UHF-1 process. This amplifier features a TTL/CMOS compatible disable control, pin 8, which when pulled low reduces the supply current and forces the output into a high impedance state ...

... Optional GND Pad (Die Use Only) for TTL Compatibility The die version of the HFA1145 provides the user with a GND pad for setting the disable circuitry GND reference. With symmetrical supplies the GND pad may be left unconnected, or tied directly to GND. If asymmetrical supplies (e.g. +10V, 0V) are utilized, and TTL compatibility is desired, die users must connect the GND pad to GND ...
