Pin Descriptions

All device inputs and outputs are HCSL unless described otherwise.

The I/O column uses the following symbols: I – input, IPU – input with 300 kΩ internal pull-up resistor, IPD – input with

300 kΩ internal pull-down resistor, IAPU – input with 31 kΩ internal pull-up resistor, IAPD – input with 30 kΩ internal pull-

down resistor, IAPU/APD – input biased to VDD/2 with 60 kΩ internal pull-up and pull-down resistors (30 kΩ equivalent),

O – output, I/O – Input/Output pin, NC – No connect pin, P – power supply pin.

IN0_p

IAPD

IAPU/APD

Input Differential or Single Ended Reference

Input frequency range 0 Hz to 600 MHz.

Non-inverting inputs (_p) are pulled down with internal 30 kΩ pull-down

resistors. Inverting inputs (_n) are pulled up and pulled down with 60 kΩ

internal resistors (30 kΩ equivalent) to keep inverting input voltages at

VDD/2 when inverting inputs are left floating (device fed with a single

ended reference).
