BA823F
Standard ICs 8-bit, serial IN, parallel OUT driver BA823 / BA823F The BA823 and BA823F are 8-bit serial input, parallel output drivers. These monolithic ICs were developed as drivers for thermal printing heads, LED character displays, and other similar applications. Applications • Thermal printing head drivers LED character display drivers Features • 1) Can drive up to 200 mA. 2) Controlling the strobe terminal with the drive timing pulse enables current to be reduced when drive is not being carried out. 3) Using the data output terminal for the next data input enables cascade connections. 4) The digital ground and power ground are separated. 5) TTL and CMOS drive possible. •Block diagram O0 12 O1 11 O2 10 O3 9 O4 8 O5 7 O6 6 O7 5 16 VCC STROBE INPUT S 1 D Q C SHIFT PULSE C 2 D Q C D Q C D Q C D Q C D Q C D Q C D Q C 3 DATA OUTPUT Do DATA INPUT DI 15 13 GND1 4 GND2 14 GND (Dig) •Absolute maximum ratings (Ta = 25°C) Parameter Power supply voltage BA823 Power dissipation Input vol.
