TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MA2573FK
Low-Voltage Octal D-Type Latch with 3.6 V Tolerant Inputs and Outputs
The TC7MA2573FK is a high performance CMOS octal D-type latch. Designed for use in 1.8 V, 2.5 V or 3.3 V
systems, it achieves high speed operation while maintaining the
CMOS low power dissipation.
It is also designed with over voltage tolerant inputs and
outputs up to 3.6 V.
This 8 bit D-type latch is controlled by a latch enable input
(LE) and an output enable input (OE).
When the OE input is high, the eight outputs are in a high
impedance state.
The 26 Ω series resistor helps reducing output overshoot and
undershoot without external resistor.
All inputs are equipped with protection circuits against static
discharge.
Features
• 26 Ω series resistors on outputs.
• Low voltage operation: VCC = 1.8~3.6 V
• High speed operation: tpd = 5.1 ns (max) (VCC = 3.0~3.6 V)
t
pd = 6.1 ns (max) (VCC = 2.3~2.7 V)
t
pd = 9.8 ns (max) (VCC = 1.8 V)
• 3.6 V tolerant inputs and outputs.
• Output current: IOH/IOL = ±12 mA (min) (VCC = 3.0 V)
I
OH/IOL = ±8 mA (min) (VCC = 2.3 V)
I
OH/IOL = ±4 mA (min) (VCC = 1.8 V)
• Latch-up performance: −300 mA
• ESD performance: Machine model ≥ ±200 V
Human body model ≥ ±2000 V
• Package: VSSOP (US)
• Power down protection is provided on all inputs and outputs.
Weight: 0.03 g (typ.)

Note 1: Exceeding any of the absol ute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temp erature/current/voltage and the
significant change in temperature, etc.) ma y cause this product to decreas e in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliabilit y upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Der ating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
