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.
