TTL74245_TypeC.nsl

Function

8bit bidirection bus x 2port code. NSL version of TTL74245 standard logic.

I/O signal

Port_A=8bit bidirection bus.
Port_B=8bit bidirection bus.
DIR=Direction．’1′ is Port_A to Port_B, ‘0′ is Port_B to Port_A.
nOE=Output enable．’0′ is active. ‘1′ is turn off and Hi-Z.

Specification

This code shown function input signal and hi-impedance signal example.
‘any { … }’ block control data output operation by ‘DIR’ and ‘nOE’ signals.

An output port which is declared as ‘output’ or ‘inout’, and is is not controlled any signal, thus it port will be ‘Hi-Z’ state.
