Product data sheet
General description
The 74LVT244B; 74LVTH244B is a high-performance BiCMOS product designed for VCC
operation at 3.3 V.
This device is an octal buffer that is ideal for driving bus lines. The device features two
output enable inputs (1OE and 2OE), each controlling four of the 3-state outputs.

The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which
are detrimental to reliability.
For SO20 packages: above 70 °C derate linearly with 8 mW/K.
For SSOP20 and TSSOP20 packages: above 60 °C derate linearly with 5.5 mW/K.

Typical values are measured at Tamb = 25 °C.
Unused pins at VCC or GND.
This is the bus hold overdrive current required to force the input to the opposite logic state.
This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 3.3 V ± 0.3 V a transition time
of 100 μs is permitted. This parameter is valid for Tamb = 25 °C only.
ICC is measured with outputs pulled to VCC or GND.
This is the increase in supply current for each input at VCC - 0.6 V.
