HD74ALVC162835A

18-bit Universal Bus Driver with 3-state Outputs

ADE-205-294A (Z)

2nd. Edition

November 1999

Description

The HD74ALVC162835A is an 18-bit universal bus driver designed for 2.3 V to 3.6 V V_CCoperation.

Data flow from A to Y is controlled by the output enable (OE). The device operates in the transparent mode

when the latch enable (LE) is high. When LE is low, the A data is latched if the clock (CLK) input is held

at a high or low logic level. If the LE is low, the A data is stored in the latch/flip flop on the low to high

transition of CLK. When OE is high, the outputs are in the high impedance state.

To ensure the high impedance state during power up or power down, OE should be tied to V_CCthrough a

pullup registor; the minimum value of the registor is determined by the current sinking capability of the

driver.

All outputs, which are designed to sink up to 12 mA, include series dumping resistors to reduce overshoot

and undershoot.

Features

•

Supports PC133 and meets “PC SDRAM registered DIMM specification, Rev. 1.1”

V_CC= 2.3 V to 3.6 V

Typical V_OLground bounce < 0.8 V (@V_CC= 3.3 V, Ta = 25°C)

Typical V_OHundershoot > 2.0 V (@V_CC= 3.3 V, Ta = 25°C)

High output current ±12 mA (@V_CC= 3.0 V)

All outputs have series dumping resistors, so no external resistors are required

t_pd(CLK to Y) = 3.5 ns (Max) (@V_CC= 3.3±0.3 V, C_L= 50 pF, Ta = 0 to 85°C)

t_pd(CLK to Y) = 2.5 ns (Max) (@V_CC= 3.3±0.3 V, C_L= 30 pF, Ta = 0 to 85°C)
