µPD23C32040AL, 23C32080AL are 33,554,432 bits mask-programmable ROM. The word organization is selectable (BYTE mode: 4,194,304 words by 8 bits, WORD mode: 2,097,152 words by 16 bits). The active levels of OE (Output Enable Input) can be selected with mask-option. The µPD23C32040AL and µPD23C32080AL are packed in 48-pin PLASTIC TSOP(I) and 44-pin PLASTIC SOP.

The document provides information about the UPB100474AB-5 supplier, but does not mention the features and characteristics of the product.

The PS7141E-1A and PS7141EL-1A are solid state relays with GaAs LEDs on the input side and MOS FETs on the output side. They are suitable for analog signal control due to their low offset and high linearity. The PS7141EL-1A has a surface mount lead design.

The PS7205B-1A is a low on-state resistance solid state relay from NEC. It has features such as low on-state resistance, large continuous load current and high switching speed. It is suitable for use in PLC circuits.

The PS2815-1 and PS2815-4 are optically coupled isolators containing GaAs light emitting diodes and an NPN silicon phototransistor in a plastic SSOP for high density applications. The product features AC input response, high current transfer ratio, high isolation voltage, and small and thin package.

This document describes the features and characteristics of the PS2841-4A and PS2841-4B photocouplers, including ultra small size, high current transfer ratio, and high isolation voltage.

This document describes the characteristics of PS2533-1 and PS2533L-1 optically coupled isolators, including high collector to emitter voltage (VCEO = 350 V), high Isolation voltage (BV = 5 000 Vr.m.s.), high current transfer ratio (CTR = 4 000% TYP.), high-speed switching (tr, tf = 100 µs TYP.) etc.

The PS7206-1A is a low on-state resistance solid state relay with large continuous load current and low on-state resistance, suitable for PLC applications.

The PS2561A-1 is an optically coupled isolator from NEC Electronics with high isolation voltage (BV = 5 000 Vr.m.s.) and lead-free product.

The PS7241E-1A is an optically coupled element from NEC Electronics that combines a GaAs infrared LED on the input side with a normally-open MOS FET on the output side to realize an excellent cost performance. The small, thin package and high sensitivity of this element makes it ideal for battery-driven mobile devices, and its small offset voltage at power-on and good linearity are also make it suitable for controlling micro analog signals.

The PS9552, PS9552L1, PS9552L2 and PS9552L3 are optically coupled isolators containing a GaAlAs LED on the input side and a photo diode, a signal processing circuit and a power output transistor on the output side on one chip. The PS9552 Series is designed specifically for high common mode transient immunity (CMR), high output current and high switching speed. The PS9552 Series is suitable for driving IGBTs and MOS FETs.
