ORDERING INFORMATION
SPECIFICATIONS
Electrical Ratings
Input Voltage: 5.0 ± 5% Vdc or 5-26 Vdc
Input Current Requirements: 40 mA
maximum plus interface loads
Ripple Current: 2% peak-to-peak @ 5 Vdc
Output Circuits: TTL Compatible
VOH >3.80v@-8mA, VOL<0.44v@8mA
VOH >2.50v@-20mA, VOL<0.50v@20mA
Output Format:
Gray code or Binary Code: 8-bit, single turn,
single ended. Gray code option utilizes low
true Chip Enable (CE’) that is pulled down with
internal 10K resistor. Positive TTL signal to
CE’ will force the 8-bit outputs to tri-state
condition allowing for shared data paths
between
microprocessor bus interfacing.
