Product details

Overview

HCF4027M013TR from STMicroelectronics is a dual J-K master-slave flip-flop in SO-16 package, operating from 3V to 20V supply, with static state retention, 16MHz typical toggle frequency at 10V, and independent asynchronous Set/Reset inputs. It performs synchronous control and register functions in digital timing and sequencing circuits.

For engineers reviewing the HCF4027M013TR datasheet, HCF4027M013TR pinout, HCF4027M013TR application, or HCF4027M013TR equivalent, key selection criteria include VDD range (3–20V), propagation delay (45–300 ns), input leakage (±0.1 µA max at 18V), symmetrical output drive (±1.15 mA at 5V), and JEDEC JESD13B compliance for B-series CMOS devices.

Technical Context

This device implements two independent complementary-symmetry J-K master-slave flip-flops with fully buffered Q and Q̅ outputs. Each section features separate J, K, Clock, Set, and Reset terminals, enabling synchronous data latching on clock's positive edge and asynchronous state forcing via Set/Reset.

Operation is static: state is retained indefinitely with clock held high or low. Input logic thresholds scale with VDD (e.g., VIH = 3.5V at 5V, 7V at 10V), and noise margins meet 1V/2V/2.5V min. across 5V/10V/15V operation per JEDEC B-series specifications.

Key Specifications

Parameter	Value and Actual Design Meaning
VDD Range	3 V to 20 V - supports wide industrial supply rails without level-shifting
f_MAX (Toggle)	16 MHz typ. at VDD = 10 V - enables medium-speed sequential logic in control systems
t_PLH/t_PHL	45–300 ns - defines maximum clock-to-output latency for timing-critical state updates
I_I (Leakage)	±0.1 µA max at VDD = 18 V - ensures low standby power in battery-backed registers
IOH/IOL	±1.15 mA at VDD = 5 V - drives standard CMOS loads directly without buffering
VIH/VIL	3.5 V / 1.5 V at VDD = 5 V - provides 1 V noise margin for robust noise immunity
t_W (Clock)	20 ns min. at VDD = 15 V - sets minimum pulse width for reliable edge detection

Pinout & Package

Package: SO-16 (Small Outline, 16-pin, surface-mount, 3.9 mm body width, 1.27 mm pitch).

Pin/Terminal	Circuit Role	Design Meaning
1, 2	Q2, Q̅2	Complementary outputs of second flip-flop - enable direct feedback or differential signaling
3, 6	K2, J2	Data control inputs for second flip-flop - determine next state on clock edge
4, 12	RESET2, RESET1	Asynchronous active-high reset - forces Q = 0 regardless of clock or J/K
5, 10	J1, J2	Data control inputs for first and second flip-flops - define set behavior on clock
7, 15	Q̅1, Q1	Complementary outputs of first flip-flop - support dual-edge sampling or toggle mode
8	VSS	Negative supply reference - must be connected to system ground for proper biasing
9, 11	SET1, SET2	Asynchronous active-high set - forces Q = 1 independently of clock or J/K
13, 14	CLOCK2, CLOCK1	Positive-edge-triggered clock inputs - synchronize state changes across both sections
16	VDD	Positive supply rail - powers internal logic and output drivers; tolerant up to 20 V

Key Features

Feature	Design Value
Static operation	State retention with clock held high or low - eliminates need for continuous clocking in hold modes
Asynchronous Set/Reset	Independent, level-sensitive controls per flip-flop - enables immediate state override without clock dependency
JEDEC JESD13B compliance	Fully meets B-series CMOS specification - guarantees interoperability with legacy 4000-series logic families
Scalable voltage thresholds	VIH/VIL track VDD proportionally - maintains consistent noise margin across 5V/10V/15V operation
Symmetrical output drive	Matched VOH/VOL and IOH/IOL - ensures balanced rise/fall times and predictable fan-out

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual J-K flip-flop applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4027BE	PDIP-16 only; higher I_Q (60 µA max at 10V vs. 2 µA typ. for HCF4027M013TR); no 20V rating	Limited to through-hole assembly; less suitable for high-temp or low-power designs	Select when legacy DIP footprint required and 20V operation not needed
MC14027BDR2G	SO-16; wider temp range (−65°C to +150°C); slightly slower f_MAX (12 MHz at 15V)	Better suited for aerospace/military environments; lower speed margin in high-frequency sequencers	Select when extended temperature compliance outweighs 20% speed penalty

Compared with CD4027BE and MC14027BDR2G, HCF4027M013TR offers superior voltage range (up to 20V), lowest typical quiescent current, and optimal speed-power trade-off for industrial control and test equipment where SO-16 surface-mount reliability and 16MHz toggle performance are critical.

FAQ

Is HCF4027M013TR pin-compatible with CD4027BE?

Yes - both use identical SO-16 and DIP-16 pinouts per JEDEC MS-012 and MS-001 standards. Pin functions (J1/K1/CLOCK1/SET1/RESET1/Q1/Q̅1, etc.) match exactly, enabling direct substitution in SO-16 layouts. However, HCF4027M013TR supports up to 20V VDD versus CD4027BE's 18V absolute max, and exhibits lower quiescent current.

What is the minimum clock pulse width required at 15V operation?

At VDD = 15 V, the minimum clock pulse width (t_W) is 20 ns, as specified in the Dynamic Electrical Characteristics table. This ensures reliable master-slave triggering and avoids metastability. Pulse widths below this value may result in undefined output states or failure to toggle.

Does HCF4027M013TR support true toggle mode?

Yes - when J and K inputs are tied high, the device operates in toggle mode: each positive clock edge inverts Q output. This is confirmed by the truth table (J=K=H → Q toggles) and supported by f_MAX ratings measured in toggle configuration (e.g., 24 MHz max at 15V).

Can Set and Reset be used simultaneously on the same flip-flop?

No - asserting both Set and Reset high simultaneously violates the truth table's defined states and results in an invalid, metastable condition. The datasheet specifies "S=H, R=H" as undefined (X). Design practice requires mutual exclusion, typically enforced via external gating or priority logic.
