Rev. 03 — 3 March 2006
Product data sheet
1. 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.
2. Features
I Octal bus interface
I 3-state buffers
I Speed upgrade of 74LVT244A
I Output capability: +64 mA and −32 mA
I TTL input and output switching levels
I Input and output interface capability to systems at 5 V supply
I Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs
I Power-up 3-state
I Live insertion and extraction permitted
I No bus current loading when output is tied to 5 V bus
I Latch-up protection:
N JESD78: exceeds 500 mA
I ESD protection:
N HBM EIA/JESD22-A114-C exceeds 2000 V
N MM EIA/JESD22-A115-A 200 V

[3] This is the bus hold overdrive current required to force the input to the opposite logic state.
[4] 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.
[5] ICC is measured with outputs pulled to VCC or GND.
[6] This is the increase in supply current for each input at VCC − 0.6 V.
