UDN-2541B

The UDN-2541B has the following features including TTL, CMOS, PMOS, NMOS Compatible;1.5 A Continuous Output Current;Efficient Input/Output Pin Structure;Low Output Saturation Voltage;SN75437NE Equivalent.

COMBINING NANI) LOGIC GATES and high-current bipolar outputs, the four power and relay drivers in this series can provide interface be-tween low-level signal-processing circuits and medium-power loads in extremely harsh environments. Each of the four independent outputs of these devices can sink up to I .5 A in the ON state.Type CIDN-2541B1W and IJDN-2542B/W integrated circuits differ only in output-voltage ratings and high-current saturation limits. Types UDN-2541B and UDN-2541 W are rated at 60 V and 1.25 A. Types UDN-2543B and UDN-2542W are rated at I.0 A with w breakdown voltage of greater than 80 V. All devices have a minimum output sustwining voltage of 35 V. Inputs are compatible with most TTL. DTL, LSTTL, and 5 V to IS V CMOS wnd PMOS logic.

Types UDN-2541 B and UDN-2542B are supplied in l6-pin dual in-line packages with heat-sink contact tabs. This configuration enebles easy attachment of an inexpensive heat sink and fits a standard integrated circuit socket or printed wiring board lay-out. The outputs include transient suppression diodes for inductive loads such as relays, solenoids and d-c and stepping motors.Types UDN-2541W  and  UDN-2542W, with higher power-dissipation ratings, are in 12-pin single in-line power-tab packages that allow efficient attachment of external heat sinks for maximum allowable package power dissipation. The tab is at groud potential and needs no insulation. These devices are used to drive high-current incandescent lamps.LEDs, heaters, and (with external transient suppression) high-voltage inductive loads.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics. Before ordering, purchasers are advised to contact the Sensitron Semiconductor sales department for the latest version of the datasheet(s).In cases where extremely high reliability is required (such as use in nuclear power control, aerospace and aviation, traffic equipment,medical equipment, and safety equipment), safety should be ensured by using semiconductor devices that feature assured safety or by means of users' fail-safe precautions or other arrangement.
