描述 Description

The NLSV4T3234 is a 4-bit configurable dual-supply bus buffer level translator. The input (B-) and output (A-) ports are designed to track two different power supply rails, VCCB and VCCA respectively. Both supply rails are configurable from 0.9V to 4.5V allowing universal low-voltage translation from the input (B-) to the output (A-) port.

特性 Features

? Wide VCCA and VCCB Operating Range
? Allows customers to translate between : 0.9 V to 4.5 V
? High-Speed w/ Balanced Propagation Delay: 2.4 ns max at 3.0 to 3.6 V
? Minimizes skew between channels
? 26Series Resistors at Output (A-) Ports 26Series Resistors at Output (A-) Ports
? Reduces ground bounce
? Inputs OVT to 4.5 V
? Vcc can be lower than input voltage without damage to device
? Non-preferential VCC Sequencing
? Easier to implement design
? Outputs at 3-State until Active VCC is reached
? Minimizes power consumption while device is in sleep mode
? Power-Off Protection
? When Vcc goes to Zero and power is still applied to I/O there is no risk of damage to device
? Ultra-Small packaging: 1.41 mm x 2.04 mm FlipChip11
? Reduces the PCB board space requirment (Great for handheld applications)
