2. 2. 2. 2. GeneralGeneralGeneralGeneral
The 74LCX244FT is a high-performance CMOS octal bus
buffer. Designed for use in 3.3-V systems, it achieves high-speed
operation while maintaining the CMOS low power dissipation.
The device is designed for low-voltage (3.3 V) VCC applications,
but it could be used to interface to 5 V supply environment for
both inputs and outputs.
The 74LCX244FT is a non-inverting 3-state buffer having
two active-low output enables. This device is designed to be used
with 3-state memory address drivers, etc.
All inputs are equipped with protection circuits against static
discharge.

(1) Low-voltage operation: VCC = 1.65 to 3.6 V
(2) High-speed operation: tpd = 6.5 ns (max) (VCC = 3.0 to 3.6 V)
(3) Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 to 3.6 V)
(4) Power-down protection provided on all inputs and outputs
(5) Pin and function compatible with the 74 series
(74LVC/ALVC/ etc.) 244 type
Note: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.
All floating (high impedance) bus pins must have their input levels fixed by means of pull-up or pull-down
resistors.
