Texas Instruments CD74HCT367M96

Overview

CD74HCT367M96 from Texas Instruments is a high-speed CMOS hex non-inverting buffer/line driver with three-state outputs, designed for bus interface and data routing in industrial control and instrumentation systems. It features dual independent 3-state enables (OE1 controls four channels, OE2 controls two), 4.5 V to 5.5 V operation, typical propagation delay of 9 ns at VCC = 5 V and CL = 15 pF, and drives up to 15 LSTTL loads.

For engineers reviewing the CD74HCT367M96 datasheet, CD74HCT367M96 pinout, CD74HCT367M96 application, or CD74HCT367M96 equivalent, key selection criteria include its LSTTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V), wide –55°C to 125°C operating temperature range, SOIC-16 package compatibility, and precise three-state timing behavior under bus-loading conditions.

Technical Context

The CD74HCT367M96 implements six independent non-inverting buffer gates partitioned into two groups: four channels (1A1–1Y4) controlled by OE1, and two channels (2A1–2Y2) controlled by OE2. Each output supports high-current drive (±35 mA continuous) and exhibits balanced tPLH/tPHL propagation characteristics.

Its HCT logic family ensures direct compatibility with legacy LSTTL inputs while maintaining CMOS power efficiency (ICC ≤ 160 μA over temperature), and its three-state leakage current (IOZ ≤ ±10 μA) and low output impedance in active state support reliable bus contention management in shared-data-path architectures.

FAQ

What is the maximum continuous output current rating for CD74HCT367M96?

The CD74HCT367M96 has a maximum continuous output current rating of ±35 mA per channel, as specified in its Absolute Maximum Ratings table. This rating applies across the full operating temperature range (–55°C to +125°C) and ensures reliable drive capability into heavy capacitive or resistive loads without thermal shutdown or parametric shift. The CD74HCT367M96 maintains this rating under both sourcing and sinking conditions, supporting bidirectional bus loading scenarios.

Does CD74HCT367M96 support operation at 3.3 V supply voltage?

No, CD74HCT367M96 does not support 3.3 V operation. Its recommended operating supply voltage is strictly 4.5 V to 5.5 V, as defined for the HCT logic family to guarantee TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V). Attempting to operate CD74HCT367M96 at 3.3 V may result in undefined logic states, excessive ICC, or failure to meet timing specifications. For 3.3 V systems, consider TI's SN74LVC367A or compatible LVC-family devices.

How are the enable inputs OE1 and OE2 configured on CD74HCT367M96?

On CD74HCT367M96, OE1 (pin 1) and OE2 (pin 15) are active-low, asynchronous 3-state enable inputs. OE1 controls outputs Y1 through Y4 (pins 3, 5, 7, 10), while OE2 controls outputs Y1′ and Y2′ (pins 11, 13). Both enables operate independently - asserting either low places its associated outputs in high-impedance state regardless of input logic levels. The CD74HCT367M96 truth table confirms that any OE = L forces corresponding Y = Z (high-Z), with no internal synchronization or propagation delay added to the enable path.

What is the typical propagation delay of CD74HCT367M96 at 5 V and 15 pF load?

The typical propagation delay (tPD) of CD74HCT367M96 is 9 ns under conditions of VCC = 5 V, CL = 15 pF, and TA = 25°C, as documented in Section 5.5 Switching Characteristics of the TI datasheet (SCHS181E). This value represents the maximum of tPLH and tPHL transitions and is measured with input rise/fall times ≤ 6 ns. At full temperature range (–55°C to +125°C), the maximum guaranteed tPD is 38 ns, enabling reliable use in systems with ≥10 MHz clock domains.

Is CD74HCT367M96 pin-compatible with CD74HC367M96?

Yes, CD74HCT367M96 is pin-compatible with CD74HC367M96 - both share identical SOIC-16 (D) package, pin numbering, and functional pin assignments. However, they differ electrically: CD74HC367M96 operates from 2 V to 6 V and uses CMOS input thresholds, while CD74HCT367M96 requires 4.5–5.5 V and provides LSTTL-compatible inputs. Substituting CD74HCT367M96 for CD74HC367M96 in a 5 V system preserves pinout and timing but ensures robust noise immunity and legacy TTL interoperability.
