74LVT244B; 74LVTH244B
3.3 V octal buffer/line driver; 3-state
Rev. 6 — 12 August 2021
Product data sheet
1. General description
The 74LVT244B; 74LVTH244B is an 8-bit buffer/line driver with 3-state outputs. The device can
be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and
2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a
high-impedance OFF-state. Bus hold data inputs eliminate the need for external pull-up resistors to
define unused inputs

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.
