Nexperia USA Inc. 74HCT367D,653

Overview

74HCT367D,653 from Nexperia is a hex non-inverting 3-state buffer/line driver with TTL-compatible inputs, 16-pin SO16 package, -40 °C to +125 °C operating range, and propagation delay of 14 ns (typ) at VCC = 4.5 V. It serves as a bus interface and signal isolation device in digital logic systems requiring controlled output enable for shared data lines.

For engineers reviewing the 74HCT367D,653 datasheet, 74HCT367D,653 pinout, 74HCT367D,653 application, or 74HCT367D,653 equivalent, key selection criteria include TTL-level input compatibility, 3-state output timing (enable/disable times ≤ 38 ns), SO16 thermal performance (Ptot = 500 mW), and industrial temperature support.

Technical Context

The 74HCT367D,653 implements six independent non-inverting buffers, each with active-low 3-state enable control (1OE, 2OE). Its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V) ensure direct interfacing with legacy 5 V logic families without level shifting.

Dynamic operation is characterized by matched enable/disable timing (ten = tdis = 35 ns typ at VCC = 4.5 V), low output transition time (tt = 12 ns typ), and CMOS power efficiency (ICC = 8 μA typ at VCC = 5.5 V), enabling reliable bus arbitration in high-density PCB layouts.

FAQ

What is the maximum clock frequency supported by the 74HCT367D,653?

The 74HCT367D,653 does not operate as a clocked device but as a combinatorial buffer. Its 14 ns typical propagation delay (VCC = 4.5 V, CL = 50 pF) supports reliable data transfer up to approximately 35 MHz on a shared bus, assuming adequate setup/hold margins and controlled trace impedance.

Can the 74HCT367D,653 drive a 50 Ω transmission line directly?

No. With ±6 mA output drive at VCC = 4.5 V, the 74HCT367D,653 cannot terminate a 50 Ω line (requiring ~90 mA for 4.5 V swing). It is intended for point-to-point or multidrop bus loading up to 50 pF, not RF transmission line driving. Use dedicated line drivers for 50 Ω applications.

Is the 74HCT367D,653 pin-compatible with the 74HC367D?

Yes-both share identical SO16 pinout, logic function, and terminal assignments. However, the 74HC367D uses CMOS-level inputs (VIH = 3.15 V min at VCC = 4.5 V), making it incompatible with TTL sources unless pulled up. The 74HCT367D,653's TTL inputs provide guaranteed interoperability with 5 V microcontrollers.

Does the 74HCT367D,653 require external pull-up resistors on its OE pins?

No. The 1OE and 2OE inputs are active-low and fully CMOS-compatible; they draw only ±0.1 μA leakage current. When driven directly by MCU GPIOs or logic gates, no pull-ups are needed. Pull-downs may be used for default-disabled operation, but are not mandatory for functionality.
