Description
MC7448THX1400ND is an older Motorola (now Onsemi) 74-series BCD-to-7-segment display driver/decoder. It takes a 4-bit binary-coded decimal input and generates seven segment outputs (a–g) to drive a LED display, typically for digits 0–9. The device is a 5V logic part designed to be TTL-compatible, with outputs intended to drive LED segments through current-limiting resistors. The THX1400ND suffix denotes a specific packaging/lot variant; exact pinout and output behavior (sink/source) depend on the package, so consult the datasheet for your variant. Common applications include digital clocks, counters, panel meters, and other numeric readouts. Because it’s an older part, sourcing may be challenging; modern equivalents in the 74HC/74HCT families offer similar functionality with wide availability.
Equivalent
Equivalent products for MC7448THX1400ND (BCD-to-7-seg decoder/driver) include TI SN7448N, National/ON Semiconductor DM74LS48N, and Fairchild MM74LS48N. These share function and pinout families; however, verify common-anode vs common-cathode compatibility and package/pinout before substitution.
Pinout
- Pin count: 14 pins (DIP in MC74 series, e.g., MC7448THX1400ND).
- Function: BCD-to-7-segment decoder/driver for common-cathode LED displays. It takes 4-bit BCD input (A–D) and provides seven segment outputs (a–g), with control inputs for Lamp Test (LT) and Blanking (BI).
