AZ100LVEL16VRL AZ100LVEL16VRLR1 AZ100LVEL16VRLR2 AZ100LVEL16VRX MARKING AZM16R AZM16R AZM16R N/A DESCRIPTION The AZ100LVEL16VR is a specialized oscillator gain stage with high gain output buffer including an enable.
The QHG/Q ¯ HG outputs have a voltage gain several times greater than the Q/Q ¯ outputs.
The AZ100LVEL16VR provides a selectable enable that allows continuous oscillator operation.
See truth table below for enable function.
If Enable pull-up is desired in the CMOS mode, an external ≤20kΩ resistor connecting EN to VCC will override the on-chip pull-down resistor.
The AZ100LVEL16VR also provides a VBB and 470Ω internal bias resistors from D to VBB and D ¯ to VBB.
The VBB pin can support 1.
5mA sink/source current.
Bypassing VBB to ground with a 0.
01 µF capacitor is recommended.
Outputs Q/Q ¯ each have a selectable on-chip pull-down current source.
See truth table below for current source functions.
External resistors may also be used to increase pull-down current to a maximum total of 25mA.
Outputs QHG/Q ¯ HG each have an optional on-chip pull-down current source of 10mA.
When pad/pin VEEP is left open (NC), the output current sources are disabled and the QHG /Q ¯ HG operate as standard PECL/ECL.
When VEEP is connected to VEE , the current sources are activated.
The QHG /Q ¯ HG pull-down current can be decreased, by using a resistor to connect from VEEP to VEE.
NOTE: Specifications in the ECL/PECL tables are valid when thermal equilibrium is established.
