– IDT7130/IDT7140LA
— Active: 550mW (typ.)
— Standby: 1mW (typ.)
◆
MASTER IDT7130 easily expands data bus width to 16-or-
more-bits using SLAVE IDT7140
Functional Block Diagram
NOTES:
1.
IDT7130 (MASTER):
BUSY is open drain output and requires pullup resistor.
IDT7140 (SLAVE):
BUSY is input.
2.
Open drain output: requires pullup resistor.
◆
On-chip port arbitration logic (IDT7130 Only)
◆
BUSY output flag on IDT7130; BUSY input on IDT7140
◆
INT flag for port-to-port communication
◆
Fully asynchronous operation from either port
◆
Battery backup operation–2V data retention (LA only)
◆
TTL-compatible, single 5V ±10% power supply
◆
Military product compliant to MIL-PRF-38535 QML
◆
Industrial temperature range (–40°C to +85°C) is available
for selected speeds
◆
Available in 48-pin DIP, LCC and Ceramic Flatpack, 52-pin
PLCC, and 64-pin STQFP and TQFP
