Nonvolatile Timekeeping RAM

DESCRIPTION The DS1646 is a 128K x 8 nonvolatile static RAM with a full function Real Time Clock (RTC) which are both accessible in a Byte–wide format. The nonvolatile timekeeping RAM is function equivalent to any JEDEC standard 128K x 8 SRAM. The device can also be easily substituted in ROM, EPR

TRI-STATEÉ TTL to MOS Multiplexers/Drivers

General Description The DS1648/DS3648 and DS1678/DS3678 are quad 2-input multiplexers with TRI-STATE outputs designed to drive the large capacitive loads (up to 500 pF) associated with MOS memory systems. A PNP input structure is employed to minimize input currents so that driver loading in la
