Which TTL integrated circuit is often used to demultiplex the bus on the 8086 8088?

8-bit transparent latch

How much time is allowed for memory access when the 8086 8088 is operated with a 5 MHz clock?

roughly 800 ns

Which format is used by the Intel 8088 microprocessor?

The Intel 8088 (“eighty-eighty-eight”, also called iAPX 88) microprocessor is a variant of the Intel 8086. Introduced on June 1, 1979, the 8088 has an eight-bit external data bus instead of the 16-bit bus of the 8086….Intel 8088.

General information
Successor	80186 and 80286 (both of which were introduced in early 1982)

When result is negative then’s bit is set as?

In a computer processor the negative flag or sign flag is a single bit in a system status (flag) register used to indicate whether the result of the last mathematical operation produced a value in which the most significant bit (the left most bit) was set.

What is the functionality of TF bit of 8086 flag register?

8086 has 16-bit flag register, and there are 9 valid flag bits….Status Flags.

Flag Bit	Function
CY	This is carry bit. If some operations are generating carry after the operation this flag is set to 1
O	The overflow flag is set to 1 when the result of a signed operation is too large to fit.
