Nexperia USA Inc. 74HCT367DB,112

Overview

74HCT367DB,112 from Nexperia is a hex non-inverting 3-state buffer/line driver with TTL-compatible inputs and CMOS outputs, operating from 4.5 V to 5.5 V supply, delivering 6.0 mA output drive at V_CC = 4.5 V, and supporting industrial temperature range (−40 °C to +125 °C) in SO16 package. It enables bidirectional bus isolation in microcontroller peripheral interfaces.

For engineers reviewing the 74HCT367DB,112 datasheet, 74HCT367DB,112 pinout, 74HCT367DB,112 application, or 74HCT367DB,112 equivalent, key selection criteria include TTL-level input compatibility, 3-state enable timing (t_en = 16 ns typ @ V_CC = 4.5 V), propagation delay (t_pd = 14 ns typ), low static current (I_CC = 8 μA max), and SO16 thermal derating profile.

Technical Context

The 74HCT367DB,112 implements six independent non-inverting buffers, each with active-low 3-state output enable (1OE, 2OE). Its TTL-compatible inputs accept 2.0 V minimum HIGH and 0.8 V maximum LOW thresholds at V_CC = 4.5–5.5 V, enabling direct interfacing with legacy 5 V logic families without level shifters.

Each buffer features rail-to-rail CMOS output swing, high-impedance OFF-state leakage ≤ ±5.0 μA, and input clamp diodes allowing safe interface to voltages exceeding V_CC when used with current-limiting resistors. The device complies with JESD7A and JEDEC Level B latch-up immunity (>100 mA).

FAQ

What is the maximum clock/data rate supported by 74HCT367DB,112?

The 74HCT367DB,112 supports data rates up to approximately 35 MHz, derived from its typical propagation delay of 14 ns at V_CC = 4.5 V and CL = 50 pF. This assumes clean edges and proper termination; actual usable rate depends on system-level timing margins, load capacitance, and PCB layout parasitics.

Can 74HCT367DB,112 drive a 100 pF load reliably?

Yes - though characterized at 50 pF, the 74HCT367DB,112 maintains functional operation up to 100 pF with increased propagation delay (~29 ns max) and slightly degraded edge rates. For sustained 100 pF loads, verify timing closure in the target application and consider adding series damping resistors to suppress ringing.

Is 74HCT367DB,112 pin-compatible with 74HC367 variants?

Yes - the 74HCT367DB,112 shares identical pinout and package (SOT109-1/SO16) with 74HC367 variants, but differs electrically: HCT has TTL input thresholds (V_IH = 2.0 V min), while HC uses CMOS thresholds (V_IH = 3.15 V min at V_CC = 4.5 V). Swapping requires verifying source logic family compatibility.

Does 74HCT367DB,112 require external pull-up resistors on OE pins?

No - OE pins are active-low and internally pulled down in most configurations; however, if left floating, they default to HIGH (outputs disabled). For guaranteed startup state, tie 1OE and 2OE to GND via 10 kΩ resistors or drive actively from a controller - no pull-ups needed.
