OCTAL BUS BUFFER (3-STATE)
1/9August 2001 HIGH SPEED:
tPD = 13ns (TYP.) at VCC = 4.5V LOW POWER DISSIPATION:CC = 4μA(MAX.) at TA =25°C COMPATIBLE WITH TTL OUTPUTS : IH = 2V (MIN.) VIL = 0.8V (MAX) BALANCED PROPAGATION DELAYS: PLH ≅ t PHL SYMMETRICAL OUTPUT IMPEDANCE:
|IOH| = IOL = 6mA (MIN) PIN AND FUNCTION COMPATIBLE WITH
74 SERIES 126
DESCRIPTIONThe M74HCT126 is an high speed CMOS QUAD
BUFFER (3-STATE) fabricated with silicon gate2 MOS technology.
The device requires the 3-STATE control input G
to be set low to place the output in to the high
impedance state.
The M74HCT126 is designed to directly interface
HSC2 MOS systems with TTL and NMOS
components.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

CAPACITIVE CHARACTERISTICS 1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC
TEST CIRCUIT CL = 50pF/150pF or equivalent (includes jig and probe capacitance)
R1 = 1KΩ or equivalent
RT = ZOUT of pulse generator (typically 50Ω))
