2001 Sep 07
853-2279 27052
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
Packaged in thin very small-outline package (TVSOP) — 0.4 mm
pitch
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 impedance. This prevents floating inputs and
eliminates the need for pull up or pull down resistors.
The outputs, which are designed to sink up to 12 mA, include
equivalent 26
series resistors to reduce overshoot and
undershoot.
To ensure the high-impedance state during power up or power
down, the output-enable (OE) input should be tied to VCC through a
pullup resistor; the minimum value of the resistor is determined by
the current-sinking capability of the driver.
The 74ALVCHS162830 is characterized for operation from –40 to
+85
°C.
