3.3 V Octal transceiver with direction pin; inverting; 3-state
Rev. 4 — 23 February 2021
Product data sheet
1. General description
The 74LVT640 is an 8-bit inverting transceiver with 3-state outputs. The device features an output
enable (OE) and send/receive (DIR) for direction control. A HIGH on OE 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
2. Features and benefits

[1] The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
[2] The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed
150 °C.

[2] Unused pins at VCC or GND.
[3] 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 = 3.0 V to 3.6 V a transition time of 100 ms is permitted. This parameter is valid for Tamb = +25 °C only.
[4] This is the bus hold overdrive current required to force the input to the opposite logic state.
[5] This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
