8-Bit PIPO Shift Register with Asynchronousclear
TC74AC299P
The TC74AC299 is an advanced high speed CMOS 8-BIT PIPO
SHIFT REGISTER fabricated with silicon gate and double-layer
metal wiring C2MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
It has a four modes (HOLD, SHIFT LEFT, SHIFT RIGHT and
LOAD DATA) controlled by the two selection inputs (S0, S1).
When one or both enable ( G1 , G2 ) are high, the eight I/O
outputs are forced to the high-impedance state; however,
sequential operation or clearing of the register is not affected.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

Note 1: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result.
Note 2: All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull
down resistors.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/Derating Concept and Methods) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C should be
applied up to 300 mW.
