FAST CMOS 8-INPUT UNIVERSAL SHIFT REGISTER
Integrated Device Technology, Inc.
IDT54/74FCT299T/AT/CT
FEATURES:
* * * * Std., A and C speed grades Low input and output leakage 1A (max.) CMOS power levels True TTL input and output compatibility - VOH = 3.3V (typ.) - VOL = 0.3V (typ.) High drive outputs (-15mA IOH, 48mA IOL) Power off disable outputs permit "live insertion" Meets or exceeds JEDEC standard 18 specifications Product available in Radiation Tolerant and Radiation Enhanced versions Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked) Available in DIP, SOIC, QSOP, CERPACK and LCC packages
DESCRIPTION:
The IDT54/74FCT299T/AT/CT are built using an advanced dual metal CMOS technology. The IDT54/74FCT299T/AT/ CT 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.

NOTES: 1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at VCC = 5.0V, +25C ambient. 3. Not more than one output should be shorted at one time. Duration of the short circuit test should not exceed one second. 4. The test limit for this parameter is 5A at TA = -55C. 5. This parameter is guaranteed but not tested.
