Texas Instruments CD74HC107MTE4

Overview

CD74HC107MTE4 from Texas Instruments is a dual J-K flip-flop with asynchronous reset, negative-edge clock triggering, complementary Q/Q outputs, and buffered inputs. It operates from 2V to 6V, delivers 60MHz max clock frequency at 5V/15pF, and supports industrial temperature range (–55°C to +125°C). It is used in synchronous logic control, state machines, and clock-domain synchronization circuits.

For engineers reviewing the CD74HC107MTE4 datasheet, CD74HC107MTE4 pinout, CD74HC107MTE4 application, or CD74HC107MTE4 equivalent, this page provides verified functional identity, SOIC-14 package mapping, timing parameters (t_PLH/t_PHL, t_SU, t_H), noise immunity specs (NIL/NIH = 30% at V_CC = 5V), and validated alternatives for logic design reuse.

Technical Context

The CD74HC107MTE4 implements two independent edge-triggered J-K flip-flops sharing no internal coupling-each with dedicated J, K, asynchronous reset (active-low), and negative-edge clock inputs. Its silicon-gate CMOS architecture enables LSTTL-equivalent speed with significantly lower static power than bipolar logic.

It features hysteresis on clock inputs to suppress noise-induced false triggering, balanced propagation delays between Q and Q outputs, and fanout capability of 10 LSTTL loads over full temperature range. Reset operation is fully asynchronous and overrides clocked state changes.

FAQ

What is the maximum operating frequency of the CD74HC107MTE4?

The CD74HC107MTE4 achieves a maximum clock frequency of 60 MHz under specified conditions: V_CC = 5 V, C_L = 15 pF, and T_A = 25°C. At full industrial temperature range (–55°C to +125°C), f_MAX reduces to 23 MHz (V_CC = 6 V) or 20 MHz (V_CC = 4.5 V), per TI's switching specifications table. These values reflect guaranteed timing performance-not typical-only benchmarks.

Does the CD74HC107MTE4 support 3.3V operation?

Yes, the CD74HC107MTE4 fully supports 3.3V operation as part of its 2V to 6V supply range. At V_CC = 3.3V, it maintains valid logic thresholds (VIH ≥ 2.0 V, VIL ≤ 1.0 V), delivers 30+ MHz f_MAX, and draws <10 µA quiescent current. This makes CD74HC107MTE4 suitable for direct interfacing with 3.3V microcontrollers and FPGAs without level translation.

What is the function of the hysteresis on the clock input of the CD74HC107MTE4?

The hysteresis on the CD74HC107MTE4 clock input increases noise immunity by introducing a Schmitt-trigger-like threshold separation (~0.3×V_CC). This prevents multiple unintended toggles from slow-rising or noisy clock edges and allows input rise/fall times up to 500 ns at 4.5V - enabling use with RC-filtered clocks or long PCB traces without added buffering.

Can the CD74HC107MTE4 replace the CD74HCT107 in an existing design?

The CD74HC107MTE4 can replace CD74HCT107 only if the system uses 3.3V or variable supply (2–6V) and does not rely on strict LSTTL input compatibility. CD74HC107MTE4 has CMOS input thresholds (VIH = 3.15 V min at 4.5V), whereas CD74HCT107 accepts TTL-level inputs (VIH = 2.0 V min). Swapping requires verifying upstream driver voltage levels to avoid logic misreads.

Is the CD74HC107MTE4 pin-compatible with the SN74HC73?

No, the CD74HC107MTE4 is not pin-compatible with SN74HC73. Although both are dual J-K flip-flops with reset, their pin assignments differ: CD74HC107MTE4 places 1J/1K on pins 1/2 and 2J/2K on pins 10/11, while SN74HC73 assigns 1J/1K to pins 2/3 and 2J/2K to pins 12/13. Functional equivalence exists, but board layout revision is required for substitution.
