Nexperia USA Inc. 74HC367DB,118

Overview

74HC367DB,118 from Nexperia is a hex non-inverting 3-state buffer/line driver in SO16 (SOT109-1) package, operating from 2.0 V to 6.0 V supply, with CMOS-level inputs, ±35 mA output drive, and propagation delay as low as 8 ns at VCC = 6.0 V. It enables bidirectional bus isolation in digital logic systems such as industrial PLC I/O modules and microcontroller peripheral expansion interfaces.

For engineers reviewing the 74HC367DB,118 datasheet, 74HC367DB,118 pinout, 74HC367DB,118 application, or 74HC367DB,118 equivalent, key selection criteria include 3-state enable timing (t_en ≤ 26 ns), input clamp diode support for overvoltage-tolerant interfacing, guaranteed operation from –40 °C to +125 °C, and SO16 package compatibility with legacy PCB footprints.

Technical Context

The device implements six independent non-inverting buffers, each with active-low 3-state enable control (1OE, 2OE). Outputs enter high-impedance OFF-state when either enable input is HIGH, allowing shared-bus contention-free operation. Input clamp diodes permit use of external current-limiting resistors for interfacing signals exceeding V_CC.

It complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, supports TTL-compatible input thresholds only in the 74HCT variant (not applicable here), and exhibits latch-up immunity >100 mA per JESD78 Class II Level B. Static and dynamic parameters are fully specified across –40 °C to +125 °C.

FAQ

What is the maximum clock frequency supported by 74HC367DB,118?

The 74HC367DB,118 is not a clocked device-it has no internal clock and operates asynchronously. Its usable data rate depends on propagation delay (8 ns typ at VCC = 6.0 V) and system timing margins. For clean 50 pF bus loading, it reliably supports data transitions up to ~25 MHz in point-to-point configurations, assuming proper PCB layout and termination.

Can 74HC367DB,118 drive LEDs directly?

Yes-each output can source or sink up to ±35 mA, sufficient to drive standard 2 mA–20 mA indicator LEDs. Use a series current-limiting resistor calculated as R = (VCC − V_F) / I_LED; for a red LED (V_F ≈ 1.8 V) at 10 mA with VCC = 5 V, R ≈ 320 Ω. Avoid simultaneous full-drive on all six outputs to stay within total P_tot limits.

Does 74HC367DB,118 support mixed-voltage operation (e.g., 3.3 V inputs with 5 V VCC)?

No-input voltage levels must remain within 0 V to VCC. Applying 3.3 V inputs to a 5 V-powered 74HC367DB,118 is valid (VIH min = 3.15 V at VCC = 4.5 V), but applying 5 V inputs to a 3.3 V-powered device violates absolute maximum ratings and risks damage. Always match input logic levels to the applied VCC.

Is there a pin-compatible 74HCT367 version in SO16 package?

Yes-74HCT367D,118 uses the identical SOT109-1 (SO16) package and pinout, but features TTL-compatible input thresholds (VIH = 2.0 V min at VCC = 4.5 V). This allows direct replacement where legacy 5 V TTL logic drives the inputs, though DC and AC performance (e.g., t_pd = 14 ns typ) differs slightly from the HC variant.
