Texas Instruments CD4027BM96E4

Overview

CD4027BM96E4 from Texas Instruments is a dual J-K flip-flop IC in 16-pin SOIC package, operating from 3 V to 18 V, with 16 MHz typical toggle frequency at 10 V, static state retention, and independent set/reset inputs synchronized to positive clock edges. It serves as a synchronous control element in digital logic sequencing, register staging, and counter design.

For engineers reviewing the CD4027BM96E4 datasheet, CD4027BM96E4 pinout, CD4027BM96E4 application, or CD4027BM96E4 equivalent, key selection considerations include supply voltage range (3–18 V), propagation delay (45–130 ns at 15 V), noise margin (2.5 V at 15 V), and SOIC-16 thermal and layout compatibility for industrial logic upgrades.

Technical Context

The CD4027BM96E4 implements two independent CMOS J-K flip-flops with fully buffered Q and Q̅ outputs, each featuring asynchronous Set and Reset inputs that override clocked operation. Its complementary-symmetry structure ensures rail-to-rail output swing and low quiescent current (≤4 μA at 15 V, –55°C to +125°C).

State transitions occur on the positive-going edge of the clock signal; J and K inputs determine next-state logic per standard J-K truth table, while Set/Reset operate independently of clock timing. Input thresholds scale with VDD (VIH = 11 V min at 15 V), supporting robust noise immunity across its full operating range.

FAQ

What is the maximum clock frequency supported by CD4027BM96E4?

The CD4027BM96E4 supports a maximum clock toggle frequency of 16 MHz at VDD = 10 V and 24 MHz at VDD = 15 V under typical conditions (TA = 25°C, CL = 50 pF). At 5 V, the rated maximum is 7 MHz. These values reflect guaranteed performance across the full –55°C to +125°C operating range only when adhering to specified setup/hold times and load conditions.

Does CD4027BM96E4 support asynchronous reset functionality?

Yes, CD4027BM96E4 provides true asynchronous Set and Reset inputs (pins 4, 7, 9, 12) for both flip-flop channels. These inputs override clocked operation and force Q outputs to logic 1 (Set) or 0 (Reset) immediately upon high assertion, independent of clock state or timing - critical for fail-safe system initialization.

What package type and dimensions does CD4027BM96E4 use?

CD4027BM96E4 uses a 16-pin SOIC (D) package per TI's drawing MO-153, measuring 7.5 mm × 5.0 mm with 1.2 mm maximum height and 1.27 mm lead pitch. It features NIPDAU lead finish and is rated MSL Level-1 (unlimited floor life at ≤30°C/60% RH), compatible with standard reflow profiles up to 260°C peak.

Can CD4027BM96E4 operate from a 3.3 V supply?

Yes, CD4027BM96E4 is fully specified down to 3 V supply voltage per JEDEC JESD138. At 3.3 V, it delivers functional operation with VIH ≥ 2.0 V, VOL ≤ 0.4 V, and tPLH/tPHL ≤ 500 ns (typical), making it suitable for mixed-voltage systems interfacing with 3.3 V microcontrollers - though maximum speed is reduced to ~1.5 MHz.

How does CD4027BM96E4 differ from CD4013B in pin compatibility?

CD4027BM96E4 is not pin-compatible with CD4013B: while both are 16-pin SOIC dual flip-flops, CD4027BM96E4 assigns CLOCK1 to pin 13 and CLOCK2 to pin 3, whereas CD4013B places both clocks on pins 3 and 11. However, CD4027BM96E4 can emulate CD4013B behavior via J=K=DATA wiring and retains identical VDD (16), VSS (8), and Q/Q̅ pin locations per channel for partial layout reuse.
