18-bit to 36-bit address driver with bus hold (3-State)
74ALVCHS162830
FEATURES
Output ports have equivalent 26 series resistors, so no external
resistors are required

Diodes on inputs clamp overshoot ESD classification testing is done to JEDEC Standard JESD22.
Protection exceeds 2000 V HBM per method A114.
Latch-up testing is done to JEDEC Standard JESD78, which
exceeds 100 mA.
Bus hold on data inputs eliminates the need for external
pullup/pulldown resistors

Optimized for use with PCK953 in SDRAM module applications Balanced ±12 mA output drive Low noise, low skew
DESCRIPTION
The ALVCHS162830 address driver is designed for 2.3 V to 3.6 V VCC operation. Diodes to VCC have been added on the inputs to clamp overshoot. The bus hold feature retains the inputs’ last state whenever the input bus goes to high impeda……
