MH7803 - two phase oscillator/clock driver

Description

The MH7803 is a self contained two phase oscillator/clock driver.

It requires no external components to generate one of three primary oscillator frequencies and pulse widths.

Other frequencies can easily be obtained by programming input voltages.

Memory/Clock Drivers MH7803/MH8803 two phase oscillator/clock driver general description The MH7803 is a self contained two phase oscillator/clock driver. It requires no external components to generate one of three primary oscillator frequencies and pulse widths. Other frequencies can easily be obtained by programming input voltages. Three sets of outputs are provided: damped and un·damped MOS outputs and TTL monitor outputs. The MOS outputs easily drive 500 pF loads with less than 150 ns rise and fall times. In addition the outputs have current limiting to protect against momentary shorts to the suppl ies. The MH7803 and MH8803 are available in a 14 lead cavity DIP. The MH8803 is also available in a 14 pin molded DIP.
