HIGH-SPEED
16K x 9 DUAL-PORT
STATIC RAM
IDT7016S/L
FEATURES:
• True Dual-Ported memory cells which allow simulta-
neous access of the same memory location
• High-speed access
— Military: 20/25/35ns (max.)
— Commercial:12/15/20/25/35ns (max.)
• Low-power operation
— IDT7016S
Active: 750mW (typ.)
Standby: 5mW (typ.)
— IDT7016L
Active: 750mW (typ.)
Standby: 1mW (typ.)
• IDT7016 easily expands data bus width to 18 bits or
more using the Master/Slave select when cascading
more than one device
• M/S = H for BUSY output flag on Master
M/S = L for BUSY input on Slave
FUNCTIONAL BLOCK DIAGRAM
• Busy and Interrupt Flags
• On-chip port arbitration logic
• Full on-chip hardware support of semaphore signaling
between ports
• Fully asynchronous operation from either port
• Devices are capable of withstanding greater than
2001V electrostatic discharge
• 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, tested to military electrical specifications
DESCRIPTION:
The IDT7016 is a high-speed 16K x 9 Dual-Port Static
RAMs. The IDT7016 is designed to be used as stand-
alone Dual-Port RAM or as a combination MASTER/
SLAVE Dual-Port RAM for 18-bit-or-more wider systems.

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.
