General Description

The MM74C48 BCD-to-7 segment decoder is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement transistors. Seven NAND gates and one driver are connected in pairs to make binary-coded decimal (BCD) data and its complement available to the seven decoding AND-OR-INVERT gates. The remaining NAND gate and three input buffers provide test-blanking input/ripple-blanking output, and ripple-blanking inputs.

Features

■ Wide supply voltage range: 3.0V to 15V

■ High noise immunity: 0.45 VCC (typ.)

■ Low power TTL compatibility: fan out of 2 driving 74L

■ High current sourcing output (up to 50 mA)

■ Ripple blanking for leading or trailing zeros (optional)

■ Lamp test provision
