Nexperia USA Inc. 74HC366PW,112

Overview

74HC366PW,112 from Nexperia is a hex inverting 3-state buffer/line driver in TSSOP16 package, operating from 2.0 V to 6.0 V supply, with CMOS-level inputs, -40 °C to +125 °C temperature range, and propagation delay as low as 10 ns at VCC = 6.0 V. It serves as a bidirectional bus interface or address/data line driver in microcontroller peripheral expansion systems.

For engineers reviewing the 74HC366PW,112 datasheet, 74HC366PW,112 pinout, 74HC366PW,112 application, or 74HC366PW,112 equivalent, key selection considerations include its inverting logic function, dual active-low output enable (OE1/OE2), high-impedance OFF-state leakage < ±0.5 μA at 6.0 V, and compatibility with 5 V TTL input levels when used as 74HCT366 variant.

Technical Context

This device implements six independent inverting buffers, each with separate input and output terminals and shared 3-state control via two active-low OE pins (pins 1 and 15). Each buffer drives one output (1Y–6Y) from its corresponding input (1A–6A), with output state determined by OE1/OE2 logic: both LOW enables all outputs; either HIGH forces all outputs into high-impedance mode.

The IC uses standard CMOS silicon process with input clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are applied. Its static input thresholds scale with VCC (VIH ≥ 70% VCC, VIL ≤ 30% VCC for HC version), while dynamic performance is characterized at CL = 50 pF with tpd down to 10 ns and tt ≤ 10 ns at VCC = 6.0 V.

The following parts are listed as comparable options for similar hex inverting buffer applications.

Compared with 74HC366PW,112, the 74HCT366PW,112 offers guaranteed TTL input compatibility at 5 V while maintaining identical timing and packaging, whereas SN74LVC6T244RGYR trades inversion and input clamping for wider voltage range and lower quiescent current - making it suitable only where those specific trade-offs align with system constraints.

FAQ

What is the maximum clock/data rate supported by the 74HC366PW,112?

The 74HC366PW,112 is not a clocked device but a combinational buffer; its usable data rate depends on propagation delay and load. With tpd = 10 ns (typical at VCC = 6.0 V, CL = 50 pF), it supports clean signal transmission up to approximately 50 MHz for single-bit edges, assuming adequate setup/hold margins and proper PCB layout to minimize skew and reflections.

Can the 74HC366PW,112 drive a 100 pF load reliably?

Yes - although characterized at CL = 50 pF, the device delivers ±6.0 mA output drive at VCC = 4.5 V, enabling stable operation into 100 pF loads. However, propagation delay increases to ~25 ns and transition time extends to ~15 ns at that capacitance, requiring timing budget verification in high-speed designs.

Is there a non-inverting version of this part in the same package?

Yes - the 74HC367PW,112 is the functional complement: hex non-inverting 3-state buffer in identical TSSOP16 package, with same supply range, temperature rating, pinout, and electrical specifications except logic polarity.

How does the dual OE architecture improve system design?

The separate OE1 and OE2 inputs allow independent control of two groups of three buffers (e.g., OE1 for channels 1–3, OE2 for 4–6), enabling partial bus gating, staggered enable sequencing, or redundancy management - unlike single-OE variants that force all six outputs to change state simultaneously.
