19-1592; Rev 2; 5/01 1 Ω , Low-Voltage, Single-SupplySPDT Analog SwitchesMAX4624/MAX4625General DescriptionFeatures The MAX4624/MAX4625 are low-on-resistance, low- ♦ Low RON voltage single-pole/double-throw (SPDT) analog switch- 1 Ω max (+5V Supply) es that operate from a single +1.8V to +5.5V supply. 2 Ω max (+3V Supply) The MAX4624 has break-before-make switching; the MAX4625 has make-before-break switching. These ♦ 0.12 Ω max RON Flatness (+5V Supply) devices also have fast switching speeds (tON = 50ns ♦ Overcurrent Protection max, tOFF = 50ns max). ♦ When powered from a +5V supply, the MAX4624/ +1.8V to +5.5V Single-Supply Operation MAX4625 offer 1Ω max on-resistance (RON), with 0.12Ω ♦ Available in SOT23 Packages max RON matching and flatness. The digital logic inputs are TTL compatible when using a single +5V ♦ Fast Switching: tON = 50ns max, tOFF = 50ns max supply. These switches also feature overcurrent protec- ♦ TTL-Logic Compatible (+5V Supply) tion to prevent damage from short circuits and exces- sive loads. ♦ Pin Compatible with MAX4544 The MAX4624/MAX4625 are pin compatible with the ♦ Guaranteed Break-Before-Make (MAX4624) MAX4544 and are available in space-saving standard ♦ Guaranteed Make-Before-Break (MAX4625) 6-pin SOT23 packages, as well as the 1.0mm high Thin SOT package.
