74ALVCHS16283018-bit to 36-bit address driver with bus hold (3-State)

FEA TURES

•Output ports have equivalent 26 Ω 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
V

operation.

CC

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 Ω series resistors to reduce overshoot and
undershoot.

To ensure the high-impedance state during power up or power
down, the output-enable (OE
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.
