Digital Attenuator, 15 dB, 4-Bit, TTL Driver, DC - 4.0 GHz
Pin Configuration
3. Pins 10 & 29 must be isolated.
4. Pin 19 must be connected to Pin 32.
5. Pin 25 must connect to Pin 30.
6. A .01 µF cap must be connected between Pins 21 and 23.
7. -Vee is produced internally and requires a .1 µF cap to
8. +Vcc requires a .1 µF cap to GND.
