HD74UH02 2-input NOR Gate ADE-205-015A(Z) 2nd Edition August 1993 Description The HD74UH02 is high speed CMOS two input NOR gate using silicon gate CMOS process. With CMOS low power dissipation, it provides high speed equivalent to LS-TTL series. The internal circuit of three stages construction with buffer provides wide noise margin and stable output. Features • Encapsulated in very small 5pins package of 2.9 × 1.6 × 1.1 mm, the efficiency to mount on substrate is significantly improved. • The basic gate function is lined up as hitachi uni logic series. • Supplied on embos taping for high speed automatic mounting. • Electrical characteristics equivalent to the HD74HC02 Supply voltage range: 2 to 6 V Operating temperature range: –40 to +85°C • | IOH | = IOL = 2 mA (min) Pin Arrangement IN B 1 IN A 2 GND 3 (Top view) 5 VCC 4 OUT X HD74UH02 Article Indication Type name H 3 Lot number A Absolute Maximum Ratings Item Symbol Ratings Unit Supply voltage VCC –0.5 to +7.0 V Input voltage VIN –0.5 to VCC +0.5 V Output voltage VOUT –0.5 to VCC +0.5 V Input diode current I IK ±20 mA Output diode current I OK ±20 mA Output current I OUT ±25 mA VCC/GND current I CC, I GND ±25 mA Power dissipation PT 200 mW Strage temperature Tstg –65 to +150 °C Recommended Operating Conditions Item Symbol Ratings Unit Supply voltage VCC 2 to 6 V Input voltage VIN 0 to V CC V Output voltage VOUT 0 to V CC V Operating temperature Topr –40 to +85 °C Input rise/fall time t r, t f 0 to 1000 (VCC = 2.0 V) ns 0 to 500 (VCC = 4.5 V) 0 to 400 (VCC = 6.0 V) 2 HD74UH02 Electrical Characteristics Ta = –40 to 85°C Ta = 25°C Test Conditions Item Symbol Min Typ Max Min Max Unit VCC Input voltage VIH 1.5 V 2.0 VIL Output voltage VOH VOL — — 1.5 — 3.15 — — 3.15 — 4.5 4.2 — — 4.2 — 6.0 — — 0.5 — 0.5 — — 1.35 — 1.35 4.5 — — 1.8 — 1.8 6.0 1.9 2.0 — 1.9 — 4.4 4.5 — 4.4 — 4.5 5.9 6.0 — 5.9 — 6.0 4.18 4.31 — 4.31 — 4.5 I OH = –2 mA 5.68 5.80 — 5.63 — 6.0 I OH = –2.6 mA V 2.0 V 2.0 I OH = –20 µA VIN = VIH or VIL I OL = 20 µA — 0.0 0.1 — 0.1 — 0.0 0.1 — 0.1 4.5 — 0.0 0.1 — 0.1 6.0 — 0.17 0.26 — 0.33 4.5 I OL = 2 mA — 0.18 0.26 — 0.33 6.0 I OL = 2.6 mA Input current I IN — — ±0.1 — ±1.0 Operating current I CC — — 1.0 — 10.0 V VIN = VIL 2.0 µA 6.0 VIN = VCC or GND 6.0 VIN = VCC or GND Switching Characteristics Ta = 25°C Item Symbol Min Typ Max Unit Test Conditions Output rise/fall time t TLH — 5 10 ns See Test circuit — 7 15 ns See Test circuit t THL Propagation delay time t PLH t PHL (CL = 15 pF, tr = tf = 6 ns, VCC = 5 V) 3 HD74UH02 Ta = –40 to 85°C Ta = 25°C Test Conditions Item Symbol Min Typ Max Min Max Unit VCC Output rise/fall time t TLH — 50 125 — 155 ns 2.0 t THL — 14 25 — 31 4.5 — 12 21 — 26 6.0 Propagation delay time t PLH — 48 100 — 125 t PHL — 12 20 — 25 4.5 — 9 17 — 21 6.0 CIN — 5 10 — 10 Equivalent capacitance CPD — 10 — — — Input capacitance ns pF 2.0 See Test circuit See Test circuit — — (CL = 50 pF, tr = tf = 6 ns) Note: CPD is equivalent capacitance inside of the IC calculated from the operating current without load (see test circuit).
