Description

The 74LVTH16245BDGG is one member of the SN74LVTH16245 family which designed as the 16-bit (dual-octal) noninverting 3-state transceivers. This device is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the A-port outputs or place both output ports into the high-impedance mode. The device transmits data from the A bus to the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports is always active and must have a logic HIGH or LOW level applied to prevent excess Icc and Iccz.

Features of the 74LVTH16245BDGG are:(1)members of the texas instruments widebus family;(2)state-of-the-art advanced bicmos technology (abt) design for 3.3-v operation and low static-power dissipation;(3)support mixed-mode signal operation (5-v input and output voltages with 3.3-V Vcc);(4)support unregulated battery operation down to 2.7 V;(5)typical VOLP (output ground bounce) <0.8 V at Vcc=3.3 V, TA=25°C;(6)distributed vcc and gnd pins minimize high-speed switching noise;(7)flow-through architecture optimizes PCB layout;(8)bus hold on data inputs eliminates the need for external pullup/pulldown resistors;(9)latch-up performance exceeds 500 mA per JESD 17.

The absolute maximum ratings of the 74LVTH16245BDGG can be summarized as:(1)supply voltage range:-0.5 to 4.6 V;(2)input voltage range:-0.5 to 7 V;(3)voltage range applied to any output in the high-impedance or power-off state:-0.5 to 7 V;(4)voltage range applied to any output in the high state:-0.5 VCC+0.5 V;(5)current into any output in the low state:128 mA;(6)storage temperature range:-65 to 150 °C.If you want to know more information such as the electrical characteristics about the 74LVTH16245BDGG,please download the datasheet in www.seekic.com or www.chinaicmart.com.
