Description
Voltage reference supply pin, 2.5 V nominal (3.0 V maximum)
Digital-to-Analog 1, voltage output. Output between 0.0 V and V
Sign 1, TTL/CMOS level. To be connected directly to NJM377x phase input. Databit D7 is transfered non
inverted from NJU39612 data input.
Voltage Drain-Drain, logic supply voltage. Normally +5 V.
Write, TTL/CMOS level, input for writing to internal registers. Data is clocked into flip flops on positive
edge.
Data 7, TTL/CMOS level, input to set data bit 7 in data word.
Data 6, TTL/CMOS level, input to set data bit 6 in data word.
Data 5, TTL/CMOS level, input to set data bit 5 in data word.
Data 4, TTL/CMOS level, input to set data bit 4 in data word.
Data 3, TTL/CMOS level, input to set data bit 3 in data word.
Data 2, TTL/CMOS level, input to set data bit 2 in data word.
Data 1, TTL/CMOS level, input to set data bit 1 in data word.
Data 0, TTL/CMOS level, input to set data bit 0 in data word.
Address 0, TTL/CMOS level, input to select data transfer, A0 selects between cannel 1 (A0 = LOW) and
channel 2 (A0 = HIGH).
Not connected
Chip Select, TTL/CMOS level, input to select chip and activate data transfer from data inputs. LOW level
= chip is selected.
Voltage Source-Source. Ground pin, 0 V reference for all signals and measurements unless otherwise
noted.
Sign 2. TTL/CMOS level. To be connected directly to NJM377x phase input. Data bit D7 is transfered
non-inverted from NJU39612 data input.
Digital-to-Analog 2, voltage output. Output between 0.0 V and V
Reset, digital input resetting internal registers. HIGH level = Reset, V
internally.
