Description
The TSH94 is a quad low power high frequency op-amp, designed for high quality video signal processing. The device offers an excellent speed consumption ratio with 4.5mA per amplifier for 150MHz bandwidth. High slew rate and low noise also make it suitable for high quality audio applications. The TSH94 offers 2 separate complementary STANDBY functions:

Non-inverting Input 2 Inverting Input 2 Output 2 Standby 1 8
STANDBY 1 acting on the n 2 operator STANDBY 2 acting on the n 3 operator
These functions reduce the consumption of the corresponding operator and put the output in a high impedance state.

1. All voltage values, except differential voltage are with respect to network ground terminal 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal 3. The magnitude of input and output voltages must never exceed VCC+ +0.3V 4. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. 5. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a 1.5k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 6. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5). This is done for all couples of connected pin combinations while the other pins are floating

To put the device in standby, just apply a logic level on the standby MOS input. Because ground is a virtual level for the device, the threshold voltage is to VCC+ (VCC+- 1.6V typ, see Table 4).

Printed circuit layout recommendations
As for any high frequency device, a few rules must be observed when designing the PCB to get the best performance from this high-speed op-amp. Some recommendations are listed below, from the most important to the least important:

By-pass each power supply lead to ground with a 10F capacitor and a 10nF ceramic capacitor very close to the device. To provide low inductance and low resistance common return, use a ground plane or common point return for power and signal. Make sure all leads are wide and as short as possible, especially for op-amp inputs. This is to decrease parasitic capacitance and inductance. Use small resistor values to decrease the time constant with parasitic capacitance. Choose component sizes as small as possible (SMD). On the output, keep the capacitor load as low as possible to avoid oscillation which would degrade the circuit stability. You can also add a serial resistor in order to minimise the effect of the capacitor load.
