HD404318 Series
3. ISBY is the source current when no I/O current is flowing while the MCU timer is operating.
Test conditions:
MCU: I/O reset
Standby mode
Pins:
RESET at VCC
TEST at GND
R0, R3, R4 at VCC
D0âD8, R1, R2, R8, RA1 at Vdisp
4. This is the source current when no I/O current is flowing.
Test conditions:
Pins: R0, R3, R4 at VCC
D0âD8, R1, R2, R8, RA1 at GND
5. Applies to the HD404314, HD404316 and HD404318.
6. Applies to the HD4074318.
I/O Characteristics for Standard Pins (VCC = 4.0 to 5.5 V, GND = 0 V, Vdisp = VCC â 40 V to VCC, Ta =
â20 to +75°C, unless otherwise specified)
