5474/DM5474/DM7474 Dual Positive-Edge-Triggered D Flip-Flops with Preset/Clear and Complementary Outputs
National Semiconductor DM7446A DM5447A/DM7447A handbook
This document describes the features and characteristics of TL6518 DM7446A DM5447A DM7447A BCD to 7-segment decoders/drivers, including circuits with active-low outputs, full ripple-blanking input/output controls, lamp test input, automatic leading and trailing zero-blanking control, etc. The products have features such as lamp intensity modulation capability, open-collector outputs for driving indicators directly, lamp test provision, leading-trailing zero suppression, etc.
National Semiconductor DM5445/DM7445 handbook
This document describes the features and characteristics of TL6517 DM5445 DM7445 BCD-to-decimal decoders-drivers. It consists of eight inverters and ten four-input NAND gates, which are used to decode BCD input data into outputs. Full decoding of BCD input logic ensures that all outputs remain off for all invalid (10-15) binary input conditions. These decoders feature high-performance NPN output transistors designed for use as indicator-relay drivers or as open-collector logic-circuit drivers. The high-breakdown output transistors are compatible for interfacing with most MOS integrated circuits.
National Semiconductor 5442A/DM5442A/DM7442A handbook

National Semiconductor DM7439 handbook
DM7439 is a digital logic chip produced by National Semiconductor Corporation. It contains 4 independent gates, each with 2 data inputs, and each gate performs the logic NAND function.
National Semiconductor 5437/DM5437/DM7437 handbook
5437�DM5437�DM7437 Quad 2-Input NAND Buffers is a circuit device released by National Semiconductor Corporation, which has four independent gates, each of which performs the logic NAND function.
National Semiconductor 54283/DM74283 handbook
The 54283 is a 4-bit binary full adder with internal carry lookahead manufactured by National Semiconductor Corporation. It accepts two 4-bit binary numbers (A0-A3 B0-B3) and a carry input (C0), and generates binary sum outputs (S0-S3) and carry output (C4) from the most significant bit. It also works with active high or active low operands (positive or negative logic)
National Semiconductor 54279/DM74279 handbook
This document describes a Quad Set-Reset Latch device called TL�F�9785 54279�DM74279, which contains four independent set-reset type flip-flops with one Q output each. The device has the characteristics of high-level output, low-level output, and indeterminate output.
