IDT70261S55PF

The IDT70261S55PF is one member of the IDT70261S family which is designed as the high-speed 16K x 16 dual-port static RAM that can be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit-or-more word systems. This device provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory.

Features of the IDT70261S55PF are:(1)True Dual-Ported memory cells which allow simultaneous access of the same memory location;(2)High-speed access: Commercial - 15/20/25/35/55ns (max.) and Industrial 20/25/35/55ns (max.);(3)Separate upper-byte and lower-byte control for multiplexed bus compatibility;(4)Busy and Interrupt Flags;(5)On-chip port arbitration logic;(6)Full on-chip hardware support of semaphore signaling between ports;(7)Fully asynchronous operation from either port;(8)TTL-compatible, single 5V (±10 %) power supply;(9)Available in 100-pin Thin Quad Flatpack;(10)Industrial temperature range (-40 to +85 ) is available for selected speeds.

The absolute maximum ratings of the IDT70261S55PF can be summarized as:(1)Terminal Voltage with Respect to GND: 0.5 to +7.0 V;(2)Temperature Under Bias: -55 to +125 ;(3)Storage Temperature: -55 to +125 ;(4)DC Output Current: 50 mA. The electrical characteristics of this device can be summarized as:(1)Input Leakage Current: 10 or 5 A;(2)Output Leakage Current: 10 or 5 A;(3)Output Low Voltage: 0.4 V;(4)Output High Voltage: 2.4 V.
