... The amplifier drives back-terminated 75Ω lines. The EL4089 is fabricated in Elantec’s proprietary Complementary Bipolar process which produces NPN and PNP transistors with equivalent AC and DC performance. The EL4089 is specified for operation over -40°C to +85°C temperature range. Pinout EL4089 (8-PIN PDIP, SO) ...

... Plastic DIP Maximum Power Dissipation vs Ambient Temperature Typical Application The EL4089 can be used to DC-restore a video waveform (see Figure 1). The circuit forces the cable driving video amplifier’s output to ground when the HOLD pin logic low. The “correction voltage” is stored on capacitor CX1, an external ceramic capacitor ...

... Likewise for RX2. The 75Ω back terminating resistor RXT is recommended when driving 75Ω cables. The board layout should have a ground plane underneath the EL4089, with the ground plane cut away from the vicinity of the V - pin, (pin 1). This helps to minimize the stray IN capacitance on pin 1 ...
