M56620AP
Bi-CMOS 8-BIT PARALLEL-INPUT LATCHED DRIVER
DESCRIPTION
The M56620AP is a semiconductor integrated circuit fabricated
using Bi-CMOS technology. It contains bipolar 8 output drivers of
CMOS latch.
FEATURES
q Enable input for output control
q Low supply current .......................................ICC≤10µA at standby
q Input level is compatible with standard CMOS
q Driver: Withstand voltage ...........................................BVCEO≥50V
Large drive current .................................. (IO(max)=500mA)
q Wide operating temperature range ..................... Ta=-20 – +75°C
APPLICATION
Thermal printer head dot driver, Relay driver, Solenoid driver
FUNCTION
When data is applied to inputs IN1 – IN8 and LATCH input is set to
“H”, the data will be latchedance with the truth table. Note that
when an “H” signal is applied to the RESET input, the latch will
maintain the reset state.
When the EN input is set to “L” and the data maintained in the latch
are “H”, the corresponding output will be ON and become “L”.
When both the LATCH and RESET inputs are “L”, the latch will
maintain the prior state irrespective of input signals IN1 – IN8.
