Nexperia USA Inc. 74HC05PW,112

Overview

74HC05PW,112 from Nexperia is a hex inverter IC with six independent open-drain outputs, designed for wired-OR/AND logic implementation in level-shifting and bus interface circuits. It operates from 2.0 V to 6.0 V, supports -40 °C to +125 °C ambient range, delivers 15 ns typical propagation delay at 4.5 V, and requires external pull-up resistors for output functionality - used in I²C bus buffering and mixed-voltage signal translation.

For engineers reviewing the 74HC05PW,112 datasheet, 74HC05PW,112 pinout, 74HC05PW,112 application, or 74HC05PW,112 equivalent, key selection criteria include open-drain drive capability, VIH/VIL thresholds across supply voltage, thermal derating behavior in TSSOP14, and compatibility with 3.3 V/5 V mixed-signal interfaces.

Technical Context

The 74HC05PW implements six identical CMOS inverters with true open-drain outputs-no internal pull-ups-enabling active-LOW wired-OR and active-HIGH wired-AND configurations when multiple outputs share a common pull-up. Each gate exhibits rail-to-rail input voltage tolerance (0 V to VCC) and sub-μA static ICC at 6.0 V.

Its functional table defines only two valid states: input LOW yields high-impedance (Z) output; input HIGH forces output LOW. Output current capability is specified at ±25 mA per channel under VCC = 6.0 V, with VOL ≤ 0.4 V at IO = 5.2 mA, ensuring reliable logic LOW assertion into standard TTL loads.

FAQ

Does 74HC05PW,112 have internal pull-up resistors on its outputs?

No. The 74HC05PW,112 features true open-drain outputs with no internal pull-ups. External pull-up resistors must be connected between each output (pins 2, 4, 6, 8, 10, 12) and the desired HIGH-level supply rail (e.g., 3.3 V or 5 V) to establish a defined logic HIGH state. This architecture enables wired-logic functions and voltage-level translation.

What is the maximum sink current per output at 5 V supply?

At VCC = 5.0 V, the 74HC05PW,112 guarantees a maximum output LOW voltage (VOL) of 0.33 V when sinking 4.0 mA, and supports up to 25 mA absolute maximum sink current per output (per limiting values table). For reliable operation within specifications, design for ≤20 mA continuous DC load per channel.

Can 74HC05PW,112 operate at 1.8 V supply?

No. The 74HC05PW,112 has a minimum recommended supply voltage of 2.0 V per Table 5. Operation below 2.0 V is outside specification and may result in undefined logic states, increased propagation delay, or failure to meet VIH/VIL thresholds. For 1.8 V systems, consider the 74LVC05 or 74AUP1G05 families instead.

Is the exposed pad on the TSSOP14 package electrically connected?

No. The exposed thermal pad on the SOT402-1 (TSSOP14) package of 74HC05PW,112 is not electrically connected to any internal node. Per Nexperia's documentation, it may remain floating or be connected to GND for thermal enhancement, but soldering it to GND imposes no electrical requirement and introduces no functional benefit beyond improved heat dissipation.
