voltage supply extremes IOL = 48mA (commercial) and 32mA (military)
CMOS power levels (1mW typ. static) TTL input and output level compatible
CMOS output level compatible Substantially lower input current levels than FAST (5µA max.) 8-input universal shift register JEDEC standard pinout for DIP and LCC Product available in Radiation Tolerant and Radiation Enhanced versions Military product compliant to MIL-STD-883, Class B Standard Military Drawing# 5962-86862 is listed on this function. Refer to section 2.
The IDT54/74FCT299 and IDT54/74FCT299A/C are built using an advanced dual metal
CMOS technology. The IDT54/ 74FCT299 and IDT54/74FCT299A/C are 8-input universal shift/storage registers with 3-state outputs. Four modes of operation are possible: hold (store), shift left, shift right and load data. The parallel load inputs and flip-flop outputs are multiplexed to reduce the total number of package pins. Additional outputs are provided for flip-flops Q0 and Q7 to allow easy serial cascading. A separate active LOW Master Reset is used to reset the register.
