Size typical 16 pin DIP body width 7.62 mm 0.3 inch, lead pitch 2.54 mm, body length about 19 to 20 mm, height about 3 to 4 mm

Pin configuration common SRAM style with CE OE WE control, DQ data pins, address pins A0 and up, VCC and GND exact mapping in datasheet

Thermal characteristics typical junction to ambient theta JA around 80 to 100 C W in still air PDIP, power dissipation depends on operating mode

Electrical properties nominal VCC 5 V, speed grade 25 ns, TTL CMOS compatible I O, current consumption depends on access rate and mode see datasheet

Lifecycle

Status mature legacy device. Availability of PDIP variants can be limited, but Y-IC can source stock and arrange production or approved substitutes

Not widely flagged as immediate end of life, but long lead times may occur. Plan ahead for lifetime buys if your design depends on PDIP

Equivalent or alternative models

- Alliance Memory families of 5 V fast SRAM in DIP including AS6C62xxx and AS6C20xxx series for similar capacities and timing options

- ISSI IS61Cxx 5 V SRAM series with PDIP options for many legacy sockets

- Renesas and other legacy 5 V SRAM families HM62xx and related series may fit some sockets

- Exact pin to pin and capacity match depends on your board. Share your capacity, pinout, and timing needs and we will provide a precise cross list
