EL7154C  
High Speed, Monolithic Pin Driver  
Features  
# Comparatively low cost  
# 3-State output  
# 3V and 5V Input compatible  
# Clocking speeds up to 10 MHz  
# 20 ns Switching/delay time  
# 4A Peak drive  
# Isolated drains  
# Low output impedanceÐ2.5X  
# Low quiescent currentÐ5 mA  
General Description  
The EL7154C 3-state pin driver is particularly well suited for  
ATE and level shifting applications. The 4A peak drive capabil-  
ity, makes the EL7154C an excellent choice when driving high  
speed capacitive lines.  
The p-channel MOSFET is completely isolated from the power  
supply, providing a high degree of flexibility. Pin (7) can be  
grounded, and the output can be taken from pin (8) when a  
‘‘source follower’’ output is desired. Then n-channel MOSFET  
has an isolated drain, but shares a common bus with pre-drivers  
and level shifter circuits. This is necessary to ensure that the  
# Wide operating voltageÐ  
4.5V16V  
n-channel device can turn off effectively when V goes below  
L
GND. In some power-FET and IGBT applications, negative  
drive is desirable to insure effective turn-off. The EL7154 can be  
used in these applications by returning V to a moderate nega-  
L
tive potential.
