TC74AC299P/F/FW
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74AC299P,TC74AC299F,TC74AC299FW
8-Bit PIPO Shift Register with Asynchronousclear
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: xxxFW (JEDEC SOP) is not available in
Japan.

Features (Note 1)(Note 2)
• High speed: fmax = 150 MHz (typ.) at VCC = 5 V
• Low power dissipation: ICC = 8 µA (max) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Symmetrical output impedance: |IOH| = IOL = 24 mA (min)

tansmission lines.
• Balanced propagation delays: tpLH ∼− tpHL
• Wide operating voltage range: VCC (opr) = 2 to 5.5 V
• Pin and function compatible with 74F299
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.
