Nexperia USA Inc. 74HCT366PW-Q100,11

Overview

74HCT366PW-Q100 from Nexperia is an automotive-qualified hex inverting 3-state buffer/line driver in TSSOP16 package, operating from 4.5 V to 5.5 V supply, delivering 6.0 mA output drive at ±0.26 V VOL/VOH, with propagation delay ≤24 ns (VCC = 4.5 V, CL = 50 pF), and qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C) for engine control and body electronics signal routing.

For engineers reviewing the 74HCT366PW-Q100 datasheet, 74HCT366PW-Q100 pinout, 74HCT366PW-Q100 application, or 74HCT366PW-Q100 equivalent, this device serves as a TTL-level-compatible, low-power, high-noise-immunity bus interface for automotive microcontroller I/O expansion, sensor data multiplexing, and CAN/LIN subsystem signal conditioning where 3-state control and input clamping are required.

Technical Context

This IC implements six independent inverting buffers, each with active-low 3-state output enable (OE1, OE2), enabling bidirectional bus control via dual enable inputs. Each channel features CMOS-compatible output structure with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5 V–5.5 V).

Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The device supports dynamic operation up to 25 MHz (based on tpd ≤24 ns and tt ≤12 ns), with CPD = 30 pF per buffer and total ICC ≤160 μA at +125 °C.

FAQ

What is the maximum clock frequency supported by the 74HCT366PW-Q100?

The 74HCT366PW-Q100 is not a clocked device but a combinational buffer; its usable frequency depends on propagation delay and load. With tpd ≤24 ns and tt ≤12 ns into 50 pF, it reliably supports data rates up to 25 MHz in point-to-point routing and bus applications where setup/hold margins exceed 5 ns.

Can OE1 and OE2 be tied together for single-enable operation?

Yes - OE1 (pin 1) and OE2 (pin 15) can be externally shorted and driven by a single controller signal. This configuration activates or disables all six buffers simultaneously, simplifying control logic at the cost of losing independent group isolation capability.

Does the 74HCT366PW-Q100 require external pull-up or pull-down resistors on inputs?

No - inputs have no internal biasing, but clamp diodes to VCC and GND allow safe use with series current-limiting resistors when interfacing to voltages beyond VCC. For unused inputs, tie directly to VCC or GND to prevent floating states and reduce leakage current.

How does the 74HCT366PW-Q100 differ from the 74HC366PW-Q100 in system design?

The 74HCT366PW-Q100 accepts TTL-level inputs (VIH ≥2.0 V), making it compatible with older 5 V MCUs and logic families, whereas the 74HC366PW-Q100 requires CMOS-level inputs (VIH ≥3.15 V at VCC = 4.5 V). This eliminates level shifters in mixed-signal automotive subsystems.
