DS7800 DS8800 Dual Voltage Level Translator
General Description
The DS7800 DS8800 are dual voltage translators designed
for interfacing between conventional TTL or LS voltage lev-
els and those levels associated with high impedance junc-
tion or MOS REF-type devices The design allows the user a
wide latitude in his selection of power supply voltages thus
providing custom control of the output swing The translator
is especially useful in analog switching and since low power
dissipation occurs in the ‘‘off’’ state minimum system power
is required
