I am Using the Part in a Circuit, it will be feed from an Oscillator eventually, but at the moment a digital Arb/Signal Generator.
I have soldered 3 up on my boards, and the output feeds a TTL Counter, and a RAM - FIFO Clock.
I am supplying the device with 5v DC,
and the input signal to both is decoupled through the 1nF Cap, and I have modified the Amplitude of square input between 0.5v to 5V P-P.
and constantly monitored output on my Scope.
But as soon as the I/P square frequency goes above about 10Mhz, the output vanishes.
Both Enables are high.
