TC74VHC299F/FW/FT
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

8-Bit Pipo Shift Register with Asynchronous Clear
The TC74VHC299 is an advanced high speed CMOS 8-BIT
PIPO SHIFT REGISTER fabricated with silicon gate 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 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.
Features (Note 1) (Note 2) (Note 3)
• High speed: fmax = 160 MHz (typ.) at VCC = 5 V
• Low power dissipation: ICC = 4 µA (max) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Balanced propagation delays: tpLH ∼− tpHL
• Wide operating voltage range: VCC (opr) = 2 to 5.5 V
• Low noise: VOLP = 1.4 V (max)
• Pin and function compatible with 74ALS299
Note: xxxFW (JEDEC SOP) is not available in
Japan.

Note 1: Do not apply a signal to A/QA to H/QH bus terminal
when it is in the output mode. Damage may result.
Note 2: All floating (high impedance) A/QA to H/QH bus
terminals must have their input levels fixed by means of
pull up or pull down resistors.
Note 3: A parasitic diode is formed between A/QA to H/QH bus
and VCC terminals. Therefore bus terminal can not be
used to interface 5 V to 3 V systems directly.
