5895 8-BIT SERIAL-INPUT, LATCHED DRIVERS Data Sheet 26182.14B- Bi MOS II 8-BIT SERIAL INPUT, LATCHED SOURCE DRIVERS The UCN5895A, UCN5895EP, and A5895SLW Bi MOS II serialinput, latched source drivers are designed for applications emphasizing low output saturation voltages and currents to -250 m A per output. These smart high-side octal, driver ICs merge an 8-bit CMOS shift register, associated CMOS latches, and CMOS control logic (strobe and output enable) with medium current emitter-follower (sourcing) outputs. Typical applications include incandescent or LED displays (both directly driven and multiplexed), non-impact (i.e., thermal) printers, relays, and solenoids. Each device is suitable for high-side applications to -250 m A per channel. The maximum supply voltage is 50 V and a minimum output sustaining voltage rating of 35 V for inductive load applications. Under normal operating conditions, the UCN5895A and UCN5895EP are capable of providing -120 m A (8 outputs continuous and simultaneous) at +65°C with a logic supply of 5 V. Similar devices, with higher output current ratings, are the UCN5890A and UCN5891A. Bi MOS II devices can operate at greatly improved data-input rates. With a 5 V supply, they will typically operate at better than 5 MHz. At 12 V, significantly higher speeds are obtained. The CMOS inputs provide for minimum loading and are patible with standard CMOS, PMOS, and NMOS circuits. TTL or DTL circuits may require the use of appropriate pull-up resistors to ensure a proper input-logic high. A CMOS serial data output allows cascading these devices in multiple drive-line applications required by many dot matrix, alphanumeric, and bar graph displays. These devices are rated for continuous operation over the temperature range of -20°C to +85°C. Because of limitations on package power dissipation, the simultaneous operation of all output drivers may require a reduction in duty cycle. The UCN5895A is supplied in a standard 16-pin dual in-line...
