I/O
Control
IDT7016 easily expands data bus width to 18 bits or more
using the Master/Slave select when cascading more than
one device
M/ S = V IH for BUSY output flag on Master
M/ S = V IL for BUSY input on Slave
Busy and Interrupt Flag
On-chip port arbitration logic
Full on-chip hardware support of semaphore signaling
between ports
Fully asynchronous operation from either port
TTL-compatible, single 5V (±10%) power supply
Available in ceramic 68-pin PGA, 68-pin PLCC, and an 80-
pin TQFP
Industrial temperature range (–40°C to +85°C) is available
for selected speeds
Green parts available, see ordering information

NOTES:
1. In MASTER mode: BUSY is an output and is a push-pull driver
In SLAVE mode: BUSY is input.
2. BUSY outputs and INT outputs are non-tri-stated push-pull drivers.
