National Semiconductor MM54C32/MM74C32 Quad 2-Input OR Gate handbook
This document describes the features and characteristics of the TLF5881 MM54C32 and MM74C32 Quad 2-Input OR Gates. These gates employ complementary MOS (CMOS) transistors to achieve low power and high noise margin. They provide the basic functions used in the implementation of digital integrated circuit systems. The N- and P-channel enhancement mode transistors provide a symmetrical circuit with output swings essentially equal to the supply voltage, resulting in high noise immunity over a wide supply voltage range. No DC power other than that caused by leakage current is consumed during static conditions. All inputs are protected against static discharge damage.

National Semiconductor MM54C195/MM74C195 4-Bit Registers handbook
The MM54C195 is MM74C195 CMOS 4-bit registers features parallel inputs, parallel outputs, J-K serial inputs, shift-load control input and a direct overriding clear. The register has two modes of operation, parallel load and shift. Parallel loading is accomplished by applying the four bits of data and taking the shift-load control of input low. The data is loaded into the associated flip-flops and appears at the outputs after the positive transition of the clock input. During parallel loading, serial data flow is inhibited. Serial shifting is accomplished synchronously when the shift-load control input is high. Serial data for this mode is entered at the J-K inputs. These inputs allow the first stage to perform as a J-K, D or T-type flip flop as shown in the truth table.
