2000 Jun 20 853–2193 23931
FEATURES
Wide supply voltage range of 1.2 V to 3.6 V
Complies with JEDEC standard no. 8-1A.
CMOS low power consumption
Direct interface with TTL levels
Current drive ± 12 mA at 3.0 V
MULTIBYTETM flow-through standard pin-out architecture
Low inductance multiple VCC and GND pins for minimum noise
and ground bounce
Output drive capability 50 transmission lines @ 85°C
Integrated 30 W termination resistors
Diode clamps to VCC and GND on all inputs
Input diodes to accommodate strong drivers
DESCRIPTION
The 74ALVC162834A is an 18-bit registered driver . Data flow is
controlled by active low output enable (OE), active low latch enable
(LE) and clock inputs (CP).
When LE is LOW, the A to Y data flow is transparent. When LE is
HIGH and CP is held at LOW or HIGH, the data is latched; on the
LOW to HIGH transient of CP the A-data is stored in the
latch/flip-flop.
The 74ALVC162834A is designed with 30 W_series resistors in both
HIGH or LOW output stages.
When OE is LOW the outputs are active. When OE is HIGH, the
outputs go to the high impedance OFF-state. Operation of the OE
input does not affect the state of the latch/flip -flop.
To ensure the high-impedance state during power up or power
down, OE 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.

NOTES:
1. CPD is used to determine the dynamic power dissipation (PD in µW):
PD = CPD × VCC2 × fi + S (CL × VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacitance in pF;
fo = output frequency in MHz; VCC = supply voltage in V ; S (CL × VCC2 × fo) = sum of outputs.
