TC74ACT373P/F/FW/FT
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74ACT373P,TC74ACT373F,TC74ACT373FW,TC74ACT373FT
Octal D-Type Latch with 3-State Output
The TC74ACT373 is an advanced high speed CMOS OCTAL
LATCH with 3-STATE OUTPUT fabricated with silicon gate and
double-layer metal wiring C2MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
This device may be used as a level converter for interfacing
TTL or NMOS to High Speed CMOS. The inputs are compatible
with TTL, NMOS and CMOS output voltage levels.
These 8-bit D-type latches are controlled by a latch enable (LE)
and a output enable input ( OE ).
When the ( OE ) input is high, the eight outputs are in a high
impedance state.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: tpd = 5.2 ns (typ.) at VCC = 5 V
• Low power dissipation: ICC = 8 μA (max) at Ta = 25°C
• Compatible with TTL outputs: VIL = 0.8 V (max)
VIH = 2.0 V (min)
• Symmetrical output impedance: |IOH| = IOL = 24 mA (min)
Capability of driving 50 Ω
transmission lines.
• Balanced propagation delays: tpLH ∼− tpHL
• Pin and function compatible with 74F373
Note: xxxFW (JEDEC SOP) is not available in
Japan.

Note:
CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load.
Average operating current can be obtained by the equation:
ICC (opr) = CPD·VCC·fIN + ICC/8 (per latch)
And the total CPD when n pcs. of F/F operate can be gained by the following equation:
CPD (total) = 20 + 12·n
