MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC74HC194 4-Bit Bidirectional Universal Shift Register High–Performance Silicon–Gate CMOS N SUFFIX PLASTIC PACKAGE 16 The MC74HC194 is identical in pinout to the LS194 and the MC14194B CASE 648–08 metal gate CMOS device. The device inputs are compatible with standard 1 CMOS outputs; with pull–up resistors, they are compatible with LSTTL outputs. ORDERING INFORMATION This static shift register features parallel load, serial load (shift right and MC74HCXXXN Plastic shift left), hold, and reset modes of operation. These modes are tabulated in the Function Table, and further explanation can be found in the Pin Description section. • Output Drive Capability: 10 LSTTL Loads PIN ASSIGNMENT • Outputs Directly Interface to CMOS, NMOS, and
