s HIGH SPEED :
f_MAX = 80MHz (TYP.) at V_CC = 6V
s LOW POWER DISSIPATION:
I_CC =4µA(MAX.) at T_A=25°C
s HIGH NOISE IMMUNITY:
V_NIH = V_NIL = 28 % V_CC (MIN.)
s SYMMETRICAL OUTPUT IMPEDANCE:
|I_OH| = I_OL = 6mA (MIN) FOR QA’ TO QH’
|I_OH| = I_OL = 4mA (MIN) FOR QA TO QH
s BALANCED PROPAGATION DELAYS:
t_PLH ≅ t_PHL
s WIDE OPERATING VOLTAGE RANGE:
V_CC (OPR) = 2V to 6V
s PIN AND FUNCTION COMPATIBLE WITH
74 SERIES 299
DESCRIPTION
The M74HC299 is an high speed CMOS 8 BIT
PIPO SHIFT REGISTER (3-STATE) fabricated
with silicon gate C²MOS technology.
This device has four modes (HOLD, SHIFT LEFT,
SHIFT RIGHT and LOAD DATA). Each mode is
chosen by two function select inputs (S0, S1).
When one or both enable inputs, (G1, G2) are

high, the eight input/output terminals are in the
high impedance state; however sequential
operation or clearing of the register is not affected.
Clear function on the M74HC299 is asynchronous
to CLOCK.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
