NJU6495
QUAD PIN ELECTRONICS DRIVER
■GENERAL DESCRIPTION
The NJU6495 is a quad pin driver fabricated in a wide voltage CMOS process. It is
designed specifically for Test During Burn In (TDBI) applications, flash memory
testers, where cost, functional density, and power are all at a premium.
■Package Outline
The NJU6495 incorporates four channels of programmable drivers into a small 64
lead LQFP package. Each channel has independent driver levels, data, and high
impedance control.
This device has a 15V output range, can operate 50MHz signal and features very
low leakage in HiZ mode. Those features enable to interface directly with TTL, ECL,
CMOS(3V, 5V and 7V), LVCMOS, and custom level circuitry, as well as high voltage
levels required for many special test modes in Flash Devices and for stressing
devices under test.
■FEATURES
● Max. 15V Output Range
● Max. 50MHz Operation
● Low Leak Current Max.2nA When Ta=25°C
● DC Output Current MaX.125mA
● PKG LQFP64-H2 (PKG size 12x12mm, 0.5mmpitch, θja=40°C/W on FR-4 4layer board)
● CMOS Process
■APPLICATION
● Burn In ATE
● Low Cost ATE
● Instrumentation

*1) This block diagram shows only 1channel. Actually this IC contains 4 channels(0 to 3).
*2) (0-3) is applied to one of a figure 0 to 3, and it shows the channel. VBB is a common in all channels.
