SN74LS442N - Brand New Texas Instruments Buffer/Driver/Transceiver
-
Description
SN74LS442N is a BCD to 7-segment decoder/driver electronic component. It belongs to the buffer/driver/transceiver product category. This component consists of NAND gates, input buffers, and seven AND-OR-INVERT gates. It offers active LOW, high sink current outputs for driving indicators directly. The SN74LS442N accepts 4-bit binary-coded-decimal (BCD) data and decodes it to drive a 7-segment display indicator. It can withstand high voltages required for 7-segment indicators and can drive indicator segments requiring up to 24 mA of current. The component incorporates automatic leading and/or trailing-edge zero-blanking control and includes lamp test provision, leading/trailing zero suppression, and input clamp diodes to limit high-speed termination effects.
