3.3 V 16-bit buffer/driver; 3-state

Rev. 13 — 12 August 2021

Product data sheet

1. General description

The 74LVT16244B; 74LVTH16244B is a 16-bit buffer/line driver with 3-state outputs. The device

can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The device features four

output enables (1OE, 2OE, 3OE and 4OE), 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

2. Features and benefits

•

16-bit bus interface

3-state buffers

•

Wide supply voltage range from 2.7 to 3.6 V

Overvoltage tolerant inputs to 5.5 V

BiCMOS high speed and output drive

Output capability: +64 mA and -32 mA

Direct interface with TTL levels

Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs

Power-up 3-state

Live insertion and extraction permitted

No bus current loading when output is tied to 5 V bus

I_OFFcircuitry provides partial Power-down mode operation

Latch-up performance exceeds 500 mA per JESD 78 Class II Level B

Complies with JEDEC standard JESD8C (2.7 V to 3.6 V)

ESD protection:

•

HBM JESD22-A114F exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

•

Specified from -40 °C to 85 °C

[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 V_CCbetween 0 V and 1.2 V with a transition time of up to 10 ms. From V_CC= 1.2 V to

V_CC= 3.3 V ± 0.3 V a transition time of 100 μs is permitted. This parameter is valid for T_amb= 25 °C only.

[5] I_CCis measured with outputs pulled to V_CCor GND.

[6] This is the increase in supply current for each input at the specified voltage level other than V_CCor GND.
