TMM2018AP-35

Manufacturer

Toshiba Electronic Devices and Storage Corporation (TAEC product). Y-IC is a quality distributor for Toshiba. We supply genuine parts and give you the best products and services, with fast response and reliable support.

Detailed Description

2K x 8-bit CMOS static RAM (SRAM), 35 ns access time, single 5 V supply, 24‑pin DIP through‑hole package. Classic 6116‑class pinout for easy drop‑in replacement in legacy designs, repairs, and prototyping.

Key Features

2K x 8 organization (2048 words x 8 bits)

35 ns read access (fast for 8‑/16‑bit buses)

Single 5 V operation, TTL/CMOS compatible I/O

Standard control signals: CE (chip enable), OE (output enable), WE (write enable)

Tri‑state outputs for bus sharing

Non‑clocked static design (no refresh needed)

Low standby power, low active power for its class

Broad ecosystem compatibility (6116‑style SRAM footprint)

Key Advantages

Simple drop‑in replacement for “6116” family SRAMs across many boards

Through‑hole DIP makes soldering, rework, and field service easy

Stable operation with classic 5 V logic; no complex power rails

Fast access improves responsiveness in time‑critical legacy systems

Proven reliability in industrial, arcade, and retro computing applications

Supported by Y-IC with genuine stock, quick delivery, and technical help

Packaging

Type: DIP‑24 (Dual‑In‑Line), through‑hole

Material: Molded epoxy plastic body, copper leadframe; tin or tin/lead plated leads depending on lot

Size: Standard 300‑mil body width (~7.62 mm), ~2.54 mm lead pitch, ~24 pins (12 per side), length ~30–32 mm

Pin configuration (typical 6116 style):

- Address: A0–A10 (11 lines for 2K words)

- Data: D0–D7 (8‑bit bus)

- Control: CE, OE, WE

- Power: VCC (5 V), GND

Thermal characteristics: Low power dissipation, no heatsink required; ensure normal airflow; follow commercial/instrument grade ambient limits

Electrical properties (typical for this class):

- Supply: 5 V nominal (check datasheet for tolerance)

- Access time: 35 ns

- TTL/CMOS input thresholds; tri‑state outputs for bus contention control

- Low standby current; modest active current (verify exact limits in datasheet)

Lifecycle

Status: Obsolete/EOL from Toshiba; legacy part. Availability is limited to existing stock and trusted distribution.

Nearing discontinuation: Yes (already discontinued in active production).
