SN74LS448N - Brand New Texas Instruments IC Chips
-
Description
Electronic Component Model: SN74LS448N
Product Category: IC Chips
The SN74LS448N is a BCD to 7-segment decoder/driver IC. It consists of NAND gates, input buffers, and seven AND-OR-INVERT gates. This low power Schottky IC offers active LOW, high sink current outputs for driving indicators directly. The IC accepts 4-bit binary-coded-decimal (BCD) and decodes this data to drive a 7-segment display indicator. It can withstand high voltages required for 7-segment indicators and has outputs that can drive indicator segments requiring up to 24mA of current. The SN74LS448N also incorporates automatic leading and/or trailing-edge zero-blanking control, lamp test provision, leading/trailing zero suppression, and input clamp diodes to limit high-speed termination effects.
Specifications and features
- Lamp Intensity Modulation Capability (BI/RBO)
- Open Collector Outputs
- Lamp Test Provision
- Leading/Trailing Zero Suppression
- Input Clamp Diodes Limit High-Speed Termination Effects
Application Scenarios
The SN74LS448N can be used in any application that requires BCD to 7-segment decoding and driving of indicators or display panels. It is commonly used in digital clocks, calculators, electronic counters, and other devices where numeric or alphanumeric displays are needed.
